Same here, this feature would be a HUGE improvement. 

I'm OK if KeePass becames a read-only interface for TeamPass. 
If I want to create/modify entries, I can access to the main application.

But it would allow all keepass features, such as completion, etc...

(at least, at first... :p)

Another solution would be to export all passwords in KeePass format, with the arborescence. 

Flat exports are not so usable. (many passwords with same name, depending on the environment)

Still surprised there are not so many +1 on this feature request, as I already know 5+ peoples who declined Teampass for this reason. :/
