Greptile SummaryThis PR changes global-hotkey activation so an inactive, non-hidden cmux reveals only visible, non-miniaturized main windows and leaves minimized windows in the Dock.
Confidence Score: 5/5The PR appears safe to merge with no actionable defects identified in the changed behavior. The target-selection change matches the stated minimized-window preservation contract, retains the hidden-application restoration fallback, and is covered by focused controller and lifecycle tests.

Reporter of #9991 here. Thanks for picking this up — the direction is right and the filter change fixes the case I reported. I built this branch's behaviour locally and confirmed the visible-plus-minimized case now works. But it doesn't fully close #9991: it trades the original bug for a state where the hotkey does nothing at all. The missing caseWhen every main window is minimized and the app is not hidden:
Repro: minimize every cmux window, click into another app (don't Hide cmux), press the hotkey. Nothing happens — the app doesn't even come forward. Same dead end if you minimize your only window while cmux is still frontmost. Before this PR that state deminiaturized and activated. The hotkey path is the only caller with no fallback: Suggested fixThe hidden branch already has exactly the right last-resort at L297; it just needs to apply to the not-hidden branch too: dismissedWindowRestoreTargets.removeAll()
- revealTargets = dismissedTargets
+ revealTargets = dismissedTargets.isEmpty
+ ? allWindows.filter { dependencies.windowOperations.isMiniaturized($0) }
+ : dismissedTargets
}Preference order then reads the same in both branches — on-screen windows first, then dismissed, then minimized only when there is nothing else to show. Minimized windows stay in the Dock whenever anything else can be revealed, and the hotkey is never inert. (Worth pulling that filter into a small helper so the two branches don't duplicate the rule.) The tell
With the fallback above, that test passes unmodified — which seems like the strongest signal that the fallback is the missing piece rather than the test being wrong. Happy to send this as a PR against your branch if that's easier than patching it yourself. |

Since this was closed, I've opened #18533 to carry the fix forward: #18533. It's your approach — the Thanks for the original diagnosis and for taking the review feedback on board — that saved me the hard part. Happy to hand it back if you'd rather reopen this one instead. |
Summary
The inactive path previously grouped visible and miniaturized windows together, then sent every target through
reveal(), which deminiaturizes its window.Fixes #9991

Fixes #9991 by keeping minimized main windows in the Dock when the global Show/Hide hotkey activates
cmuxwhile the app is inactive but visible. Previously, the hotkey revealed both visible and minimized windows; now it reveals only visible windows and restores minimized windows only when no visible or dismissed targets exist.LINUX_RUNNER, defaulting to the Blacksmith runner.Written for commit 68435c7. Summary will update on new commits.
