Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟡 Moderate · up to The log viewer improvements still omit blank lines from multiline entries, which can make displayed or saved log content incomplete; smaller issues may affect very long entries, auto-scroll behavior, and singular wording.

Learning: In the i18n JSON files, the translation key `minimizeOnClose.disabledHint` is intentionally displayed when `isTrayIconEnabled` is true and the minimize-on-close toggle is disabled. The hint text should therefore instruct the user to disable the tray icon to make the setting available. During reviews, don’t “correct” this translation for seeming mismatches with the toggle state—first confirm it matches the component’s intended behavior; only update the wording if the underlying product logic/UX requirement changes.

🚀 Performance & Scalability | 🟠 Major | ⚡ Quick win
Retain the selected entry limit during streaming.
Each tail response prepends newEntries without a limit. A viewer configured for 100 entries grows indefinitely while streaming. This bypasses the selected limit and can increase renderer memory use over long sessions.
Trim the combined entry list to entryLimit when it is not all. Keep totalEntries, timestamp bounds, and date-range metadata aligned with the retained entries.

Keep an unavailable total entry count unavailable.
prev.totalEntriesInFile ?? 0 changes an unknown file total into a known count. After the first tail update, the UI can display an incorrect “N of M entries” value.

Preserve blank continuation lines.
Line 23 removes empty and whitespace-only lines before multiline aggregation. A blank line inside a stack trace is then lost from both message and raw.
Keep all split lines after a log entry starts. Remove only the synthetic final split item when the input ends with a newline. Add a regression test in src/logViewerWindow/__tests__/parseLogs.spec.ts for a multiline entry with a blank continuation line.

Rebased onto current origin/dev after #3444. Keeps the #3444 shell (sidebar/timeline/toolbar) and ports the additive hardening from this PR: - Tail reads stop at the last newline (trimBufferToLastNewline) so mid-poll writes cannot split lines/UTF-8 characters - fs.promises everywhere in log-viewer handlers (no existsSync/statSync blocking the main event loop) - Precompute searchText/rawLower at parse time for filter matching - Auto-scroll timestamp guard so programmatic scrolls do not cancel themselves; resume pill when paused with new entries pending - Reveal log file in folder (authorized IPC → shell.showItemInFolder) - Save as plain .log alongside zip; i18n for native file dialogs - isAtLeastLevel helper retained for callers; UI keeps #3444 facet multi-select level filters Co-authored-by: Jean Brito <jeanfbrito@gmail.com>

i18next 23.7 pluralization count _one _other missing plural suffix behavior
💡 Result:
In i18next (including version 23.7), pluralization relies on the Intl.PluralRules API to determine which suffix (e.g., _one, _other, _few, _many) to append to your translation key [1][2]. The behavior regarding "missing" plural suffixes follows these key principles: 1. Mandatory Suffixes: i18next maps counts to specific CLDR plural categories [3]. If the language’s current plural rule dictates a specific category (e.g., "many" for 14 in Polish) but that suffix is missing from your JSON (e.g., key_many is undefined), i18next will not automatically fall back to _other [4]. Instead, it will fail to find the translation and return the key name (or trigger the missing key handler) [3][4]. 2. The Role of _other: The _other suffix is not a universal fallback for all missing categories; it is itself a specific CLDR category [3]. While _other is required by the CLDR specification and serves as the fallback for categories that cannot be matched otherwise, it will not be used if the PluralRules engine explicitly determines that the count belongs to a different category (like _many or _few) that is not defined in your files [3][4]. 3. Requirement of 'count': Pluralization is only triggered when the count option is provided to the t function [1][3]. If you call t('key') without {count: n}, i18next looks for the base key (e.g., 'key') and will not attempt to resolve any plural suffixes [3][4]. 4. Intl.PluralRules Dependency: i18next v23 uses the Intl API to determine these categories [2][5]. If your environment lacks this support (e.g., certain older engines), it degrades to a basic English-style rule (_one and _other only) or requires a polyfill [1][2]. To ensure consistent behavior, you must provide all CLDR-defined plural forms for the languages you support [4]. You can identify the required suffixes for a language using the browser console: new Intl.PluralRules('your-language-code').resolvedOptions.pluralCategories [4]. If you are experiencing unexpected key returns, verify that you are providing the count variable and that your JSON contains all necessary categories for that language, not just _one and _other [3][4].

Add plural forms for newEntriesPaused.
logViewerWindow.tsx passes count: pendingNewEntryCount to this translation. The current template can render “1 new entries.” Add newEntriesPaused_one and newEntriesPaused_other.
The matches key has no matching translation call in the inspected source.

MDN Element scrollTo behavior smooth scroll event scroll events emitted during smooth scrolling duration
💡 Result:
When you perform a smooth scroll using the Element.scrollTo method (or Element.scroll), multiple scroll events are emitted throughout the duration of the smooth scrolling animation [1][2]. As the browser updates the scroll position incrementally to create the smooth animation effect, it triggers the scroll event repeatedly until the destination is reached [2][3]. Key points regarding scroll events and smooth scrolling: 1. High Frequency: Because smooth scrolling involves a series of incremental position updates, the scroll event can fire at a high rate [1][2]. It is often recommended to throttle or debounce your event handlers if they perform heavy operations [1]. 2. Completion Detection: The scroll event itself does not signal the end of the animation. To reliably detect when a smooth scrolling operation has finished, you should use the scrollend event, which is specifically designed to fire once a scrolling operation—including smooth programmatic scrolls—has completed [1][4]. 3. Specification and Behavior: The CSSOM View Module dictates that user agents update the scroll position in a user-agent-defined fashion over time during a smooth scroll [3][5]. While the exact number of events can vary by browser implementation, the emission of multiple scroll events is standard behavior during the animation [2]. For modern applications, rely on the scrollend event to perform actions that must occur after the smooth scroll has finalized, rather than attempting to track the completion of the animation via the frequent, intermediate scroll events [1][4].

Keep the programmatic-scroll guard active until smooth scrolling settles.
scrollToIndex({ behavior: 'smooth' }) emits multiple scroll events during its animation. Because isAutoScrollingRef is cleared immediately, an event after AUTO_SCROLL_GUARD_MS can set userHasScrolled to true and re-suspend auto-scroll. Use scrollend or a settled-scroll debounce.

Build derived fields once per completed entry.
Both parsers lowercase the complete accumulated message and raw after every continuation line. Long multiline entries therefore require quadratic parsing work. Defer buildEntryDerivedFields until the entry is complete and before it is added to entries.

Preserve blank continuation lines in both parser implementations.
Both parsers discard blank or whitespace-only continuation lines. Retain all lines after an entry starts, and remove only the synthetic final item caused by a trailing newline. Otherwise message, raw, searchText, and rawLower omit part of the log entry.
