MOD-EDIT: 2/21/2021 Check what has been implemented.
Would be powerful if all major Obsidian modules had filtering capability.
Filter in Edit and Preview windows
Be able to show/hide heading sections, or show/hide sections that contain particular #tags or even by styles (ex. show me only code blocks or quotes in this huge, never-ending page)
Filter the Backlinks Sidebar
The way Roam does this is great.
Search Bar [DONE]
Advanced booleans, of course.
Search Bar Results
ex. Too many results? Filter with more booleans!
File Explorer
Just show me folders with recent edits. Or show me folders that contain notes with a particular #Tag like #ActiveProject
Graph View [DONE]
These two posts already mention filtering for Graph View.
Indicator
Naturally, we would need a clear visual indicator that filters are active in any particular view so we don’t freak out and think we deleted a bunch of essential information
All of this will become so valuable as our personal databases become huge.
