[DONE] Multi-panel context-preserving navigation

Getting that advanced starts to become more the realm of an Electron-based desktop app IMO. Where you could have Fibery running as a dedicated, installable app (not a PWA), and it could have multiple windows that you could perhaps flexibly rearrange, split views, etc. Sounds like a lot of work though, heh. I doubt the team will go that route. But it’s useful to know what people want/need, of course.
