Hi, I'm trying to get MultiToggle and WorkspaceCursors to play nicely with each other. Ordinarily, MultiToggle lets you apply a layout transformation to the current workspace without affecting the layouts of other workspaces. E.g. if I toggle workspace 1 to Full layout, it won't impact the layouts being used on workspaces 2, 3, etc. I've started using WorkspaceCursors (XMonad.Actions.WorkspaceCursors) to manage independent groups of workspaces, and noticed that if I use it's functions (e.g. modifyLayer) to navigate between workspaces, layout toggle states seem to bleed across workspaces rather than remaining independent per workspace. For example, starting on workspace 1 with my regular Tall layout, I navigate to workspace 2 and toggle it to Full layout. Then I go back to workspace 1 and see that it, too, has been toggled to Full layout. I can't figure out exactly what's causing this, or how to fix it so that workspace layouts toggle independently. I'm hoping someone here sees what I'm missing. I put together a minimal config to reproduce the problem: https://github.com/ivanbrennan/xmonad-testing/commit/2e9541b0937eee31ae7f300... The config provides two groups (A and B) of nine workspaces. group A: 1A 2A 3A 4A 5A 6A 7A 8A 9A group B: 1B 2B 3B 4B 5B 6B 7B 8B 9B Its layoutHook consists of: myLayoutHook = workspaceCursors cursors . avoidStruts . mkToggle1 FULL $ Tall 1 (3/100) (1/2) Keys super+1 .. super+9 use WorkspaceCursors functions to switch between workspaces within the currently active group. Keys super+ctrl+1 .. super+ctrl+2 use WorkspaceCursors functions to switch between groups A and B. Additionally, keys super+meta+1 .. super+meta+9 use traditional StackSet functions to switch between workspaces 1A .. 9A. I added these for comparison, showing that MultiToggle state is recognized per-workspace when using this form of navigation. I can't figure out the root cause. I suspect the most relevant pieces of code from WorkspaceCursors and MultiToggle are the following: https://github.com/xmonad/xmonad-contrib/blob/e60805bd45ca2feb9ef3335d023daa... https://github.com/xmonad/xmonad-contrib/blob/e60805bd45ca2feb9ef3335d023daa... Does anyone know what I might be missing, or how I could debug further to get to the root of the problem? Thanks! Ivan
