Since you’ve now written the More Flags add-on (forum page is here), any thoughts about making a colorless leech flag a standard thing?
Colorless because is:suspended cards already have a color which we wouldn’t want to override, and because traditional note-level tags don’t require you to set a color, or even let you do so.
Maybe the deck options Lapses section could have an option to set card-level “leech” status via this new flag instead of at note level via tags.
Using note-level leech tags seems like a mistake that is now set in stone.
