[FEAT]: Pin window to multiple workspaces

[bartiosze]

Is your feature request related to a problem? Please describe.
I would like to keep some of the applications available on all/some workspaces. This way, I don't need to switch to a dedicated workspace to manage the app.

Describe the solution you'd like
I had some experience with awesomeWM and one could attach a window to multiple workspaces.

Describe alternatives you've considered
I haven't dropped windows taskbar completely and I can switch to app from the taskbar (all apps on the taskbar). However, I'd like to move away from the taskbar one day and depend on komorebi only.

It might be already available and I'm too new to have discovered that:) Please forgive me if I didn't dig deep enough:)

I also would like to see this feature. I like to have some apps like my browser or chat apps open on multiple workspaces. Currently the only solution is to "unmanage" these windows, which isn't a great solution.

Actually, it may make more sense to add the sticky option to containers. Otherwise things may get weird if only one window inside a container is sticky.
