Tags and filtering
Label cards with tags, filter a board down to just the cards that match, and keep each board's tag vocabulary its own.
Colors are good for one dimension of organization; tags handle the rest. A card can carry as many tags as you like — chapter, pov-mara, needs-research, maybe-cut.
Adding tags to a card
Open a card and find the Tags tray along the bottom. Type a tag and press <kbd>Enter</kbd> (or a comma) to add it. As you type, Cork suggests tags already used on this board so your labels stay consistent — research and Research are treated as the same tag.
Remove a tag with the ✕ on its chip. Tags show as small chips at the bottom edge of cards on the board, so you can see your system at a glance.
Filtering a board by tag
In the board header, the Tags menu lists every tag on the board with a count of cards carrying it. Check one or more and the board shows only matching cards — everything else is hidden, not deleted. Cards matching any checked tag stay visible, and a stack stays visible if any card inside it matches.
While a filter is active the Tags button shows a count badge, and dragging is paused until you clear the filter (moving cards around invisible neighbors gets confusing fast). Clear filter puts everything back.
Tags are per-board
Each board keeps its own tag vocabulary. Your novel's act-one tag won't appear in suggestions on your recipes board, and filtering never pulls in cards from other boards. Reuse the same tag names across boards if you like — they simply live independently.
Tags in search
Search matches tags too: search revision and cards tagged revision appear alongside text matches. Prefix with # — like #revision — to match tags only.
