Currently re-learning & re-structuring my #Mozilla #Thunderbird @thunderbird

Discovering:
- it is impossible to run filters on folders other than inbox. I'd like to auto archive mail in specified folders older than X days...not possible?

- quick filtering mail will only work in the top folder excluding any subfolders. This makes it hard to filter mails in a year-based archive. IMNSHO search is not a solution, the results interface is very meh.

Any tips for (pls no vibecoded) addons fixes?
