Management of very many tags

Three questions about “Tags”:

  1. Is there a way to group the tags by last use or frequency of use (both in the selection lists and on the left in the side bar)?
  2. Would it be possible to display only the most frequently used (or specially selected) tags on the left-hand side bar and to collapse the rest behind a “More”, as in the case of the mailboxes?
  3. It would be great if I could combine the tags into (collapsible) groups - is there a way to activate this?

Background: I have used a lot (> 100) tags in my previous email client and am looking for ways to make their use clearer for me.

Regards or “Ade” (as a Franconian would say goodbye)
