Improve accordion layout visualization about aerospace

Thanks for the inspiration, I didn't know about stackline, it looks nice.

But it requires a lot of effort to implement smth like this. At this point, I'm happy with the effort/outcome ratio for the current accordion padding approach

Though, I'd happily consider a PR if someone implements nice indicators like this

@nikitabobko I really liked the "minimal indicators" that the stackline plugin for yabai provided. One could get rid of the current partial overlap with the other window and have the windows overlap completely instead. The indicators could then be displayed on the side or on top of the accordion depending on whether it is in vertical or horizontal layout.

Totally understood. I agree that the current approach is functional and there are other features that you probably want to spend your time on developing before considering more "eye candy" things like this one. Just thought I leave it here as a potential addition in the future. Maybe somebody more skilled than me will implement it and submit a PR :)
