[Feature Request] Retain focus after switching workspaces with more than one frame per workspace

[BettaGeorge]

The current behaviour is that if you have more than one frame (X window) on workspace A, switching to workspace A from another workspace always focuses the first frame in the list. This is not always desirable: imagine a workspace A with frames 0 and 1, where 0 displays some reference material and 1 is the document being worked on. If one is writing in frame 1, then switches to some workspace B and back, one would like to immediately continue working. However, the focus is now on frame 0, so one is forced to use the window switcher before continuing work.

I propose introducing a variable to hold the (index of the) currently focused frame of a workspace when leaving said workspace, to restore focus when returning to the workspace. If someone can point me to the code for focusing, I am happy to implement this behaviour myself and create a pull request.

A small correction, X windows are not frames in exwm parlance, they are windows. Monitors are frames. Workspaces are a collection of windows that can be shown in a frame (monitor). This is confusing I know because when not using exwm, emacs frames are X-windows. But under exwm, frames occupy an entire monitor, and xwindows are emacs windows.

I just tried creating a new workspace with multiple windows in each. Then I flipped between them with exwm-workspace-switch, and it remembered which window is the active focused window for each workspace, so I'm not quite sure what you're saying here.

I can't reproduce this either.
