Folder Search Folder

Hi,

In our company each project an an separate folder where everybody can have a look at. The problem is that we have now a huge number of folders and as we move each mail from our inbox to the project folder the only option is to use folder favorites. This work well, but have an folder search would be way easier and usefull.

here is a “mockup” how to integrate the search

Today l get the Information that in kmail move an mail can be done by

Keyboard »m« than type something from the folder name.

Does nobody has more folders and has to move the mails into folders?
