fix(code): full-width chat messages, hide scrollbar, flush input bg - #4374
Merged
Conversation
Drop #chat horizontal padding and hide its scrollbar so message blocks span the same full width as the input box (wheel/keyboard scroll still works). Match the input box background to the app background.

…angchain-ai#4374) Closes langchain-ai#3548 --- The chat surface had two nits: message blocks didn't line up with the input box (the chat container had horizontal padding the input border didn't), and the vertical scrollbar was always on unless the terminal was in ASCII mode — with no way for a user to hide it on a capable terminal. This makes the chat area flush with the input box and adds a user-toggleable scrollbar so people can choose whether the scrollbar is visible. - `#chat` drops its horizontal padding so message blocks span the same full width as the input box border below. - The input box and status bar switch from `$surface` to `$background` so they blend with the app background instead of reading as a separate band. - New `/scrollbar` slash command toggles the vertical scrollbar on or off for the current session and persists the choice to `[ui].show_scrollbar` (and `DEEPAGENTS_CODE_SHOW_SCROLLBAR` for an env-var override). It defaults to off, matching the look of other coding CLIs; wheel and keyboard scrolling still work when the scrollbar is hidden. ASCII-mode terminals keep the scrollbar hidden regardless of the preference, since they can't render the glyphs. ## Screenshots ### Before <img width="861" height="632" alt="Screenshot 2026-06-29 at 5 38 10 PM" src="https://github.com/user-attachments/assets/4add48dd-f761-4edf-a2a1-aefa9c6e4697" /> ### After <img width="862" height="634" alt="Screenshot 2026-06-29 at 5 36 48 PM" src="https://github.com/user-attachments/assets/d7ecb5b7-87b3-4122-8b28-bc61b248b670" /> <img width="857" height="634" alt="Screenshot 2026-06-29 at 5 37 19 PM" src="https://github.com/user-attachments/assets/2f656c5b-5509-4326-a68a-ad2a3a59fd6a" /> --------- Co-authored-by: Mason Daugherty <github@mdrxy.com> Co-authored-by: Mason Daugherty <mason@langchain.dev>

Closes #3548
The chat surface had two nits: message blocks didn't line up with the input box (the chat container had horizontal padding the input border didn't), and the vertical scrollbar was always on unless the terminal was in ASCII mode — with no way for a user to hide it on a capable terminal.
This makes the chat area flush with the input box and adds a user-toggleable scrollbar so people can choose whether the scrollbar is visible.
