If you want to add tags to a block, it must correspond to an existing note or block. The ability to add other tags (e.g. to track themes) would be helpful.
Hi there, the recommended workflow would be to add a note for (e.g.) a specific theme and then use that to tag the blocks. You can also give the note a color for color-coding of the blocks. Would that solve your use-case or are you thinking of something else?
This note workaround is the solution I had found also. But it has two problems.
