In previous versions, I seem to remember in at least one, if not all, of the various tag dialogs and menus showing recent tags (e.g., "What will you work on", "Add tag", "Welcome back! Would you like to tag your away time?", etc.), it would show when we last used each listed tag combination or note (if cursor in the Notes input box). Could you add that back?

(I find it particularly useful for notes because I can't always tell, with my cursor in the Notes input, which notes were previously used with the selected tag combination, and which are just "recently used" but with a different tag combination. Last used can also be useful for the tag combinations, too).
