Thanks for watching what I shared and sharing own thoughts :)
Your idea makes me think of my vague understanding of plan9.

Do you imagine something like a mind map from obsidian where things are linked or unlinked by tags?
Is the main difference that it tiles instead of floats?
Edit: oh it seems much more hotkey, terminal, and search focused watching than clicking. I think that is a much bigger difference than I originally expected.
