[horde] Rampage tags management

[Joao S Veiga]

Hello,

I'm looking at the rampage_* tables in the database (Horde 5.2.2), and  
would like to do some cleanup, but could not find a interface to  
manage the tags:

1 - Is there a way to automatically remove unused tags from horde/rampage?

2 - Is there a way to safely remove specific tags, even if in use? If  
I just remove its references from rampage_tag_stats, rampage_tagged,  
rampage_tags, and rampage_user_tags_stats, is that safe?

3 - I noticed that rampage_tag_stats and rampage_user_tags_stats  
counters never decrement (i.e., they count how many times a tag has  
been used, not how many objects are currently tagged by it). Is that  
by design? Any way of finding out which tags are actually in use  
(apart from checking the existence of each object tagged by it)?

4 - Rampage_objects keeps the object information even if the object  
does not exist anymore; for example, adding a mnemo note with a tag,  
then removing the note, creates an entry in rampage_objects which is  
left there permanently. Is that by design? Any reason for that? This  
and (3) makes it harder to find unused tags.

Thanks!
