For me, Focused View For Folders would be enough. My use case is a vault for projects, with each project in a folder. Projects may sometimes connect but are mostly separate. The fuller Zone concept that could also use tags and other things appeals to me, but I don’t have any use in mind yet.
It would be nice to be able to add multiple folders to a focus (but usually I would only need 1).
To expand on “Focused View: clicking or double clicking a Zone would filter out anything but what pertains to a zone” — I’d expect this to affect:
- Autocompletion of links and tags
- File list view
- Search
- Quick open
- Starred items (maybe?)
- Maybe other things I’m forgetting?
Should consider what happens when you follow a link to a note outside of the focus.
EDIT: There is a request just for folders: [Feature] Focus mode in file explorer — EDIT TO THE EDIT (2024-09-07): Found an older request for just folders and merged the other one into it: Focus (Hoist) a folder in the vault
