Question: extendable UI plans?

Sorry if there already is a thread that I'd missed: are there any known plans for UI changes?

I'm asking specifically because as lots of cool features are added in plugins, more flexible options might help.
For things like alternative visualizations (like graphs or kanban), or even smaller ones like backlinks or outline, things like togglable panes would be very useful.

For example, I only want to see the note graph once in a while - and when I do, I want it as big as possible. So toggling a pane, or even having it pop out as a separate window, would be handy.
Maybe something like what VS Code has?

I know this isn't exactly a top priority, and I have no idea how much work it'd be to support. I'm just curious.
