Opt in for a callback when WMUX is about to be closed #227
Description
What are you trying to do?
I had a data loss when i accidently hit the red X button on wmux because it did what it is supposed to do. It closed and with that i had no more access to my running sessions (clearly my fault). But this happened accidently because my pc was running at limit where i could barely move my mouse pointer.
What would you like wmux to do?
I would love to have an opt in feature like this:
- activate ask user whether to really close the whole wmux application
I understand that this should not be imposed on every user but for me it would be a very critical safety net (did not happen only once :/) - so my suggestion is a kind of OPT IN setting for this. Which when activated forces wmux to stay open until the user confirmed in the confirm dialog.
What do you do today instead?

feat(window): opt-in confirm before closing wmux; taskbar icon-cache …
amirlehmam commentedon Sep 9, 2026
Done in v2.10.2: Settings → Workspaces → "Confirm before closing wmux", off by default exactly as you suggested.
When it is on, the window's × button, Alt+F4 and the close-window shortcut all put up a dialog first — "Quit wmux? N terminal sessions will be terminated, including any agents running in them" — with Cancel as the default button, so a stray Enter right after the stray click cannot confirm it either. A second click on × while the dialog is up is ignored rather than opening a second dialog.
Two details worth knowing:
wmux close-windowfrom the CLI also never prompts, same rule as the existing "confirm before closing a session" guard.Sorry about the lost sessions. For what it is worth, the layout comes back on the next launch; it is the processes that do not, and this is the switch that stops that happening by accident.
