It’d be neat if there was some browser shortcut that made clicking on a card/note tag execute a search query for it (and, if further selected, also other tags).
Currently both Left Click + Ctrl/Shift causes the tags to be selected. So one modifier could be reused to launch such queries instead (preferably Ctrl).
It’d further be useful if a single-tag query (optionally) caused the tag to be selected in the sidebar – eg., when tags are alphabetically related.
