Summary

<html> <html><head></head>

Environment

  • Windows 11

  • Komorebi 0.1.37

  • Komorebi bar 0.1.37

  • whkd 0.2.7

  • Commercial licence

How I work
I switch between three set-ups:

  1. Laptop only (travelling or in a meeting)

  2. Two external monitors with the laptop closed (office)

  3. One external monitor plus the laptop screen (home)

What goes wrong
When you hot-plug or unplug a monitor, Komorebi and the bar lose track of the layout. The bar resizes or disappears, windows change size, workspaces don't have any windows on them, windows seem to float randomly. Video example:

https://github.com/user-attachments/assets/25da94d7-14c8-4e36-8556-f97fb8967512

What I expect
Komorebi should detect the new monitor layout and keep my workspaces intact. A short prompt could appear:

You changed your monitor layout. Replicate existing workspaces on the current screen? [Y/n] (10 s)

Typical case:

Office (two monitors) After unplugging (laptop only)
Monitor 1 Laptop screen
I – terminal I – terminal
II – Chrome II – Chrome
III – music III – music
IV – Teams IV – Teams
V – email V – email
Monitor 2 Floating
I – docs docs

I wouldn't mind if it took the "main" monitor's workspaces (the one with the most applications) and replicated that while other applications were floated for me to organise

The issue appears related to #989, but having to restart Komorebi and the bar every time stands out to me as a bug, not a feature

Thanks for looking into it.

Ah, my apologies - that's great it's already supported, thanks for pointing me in the right direction!
