Multiple Keepass databases opened

When having opened two kdbx files in KeePass Kee doesn’t work at all. Setting a folder as “homegroup” doesn’t have any effect. Only when closing the second file, the first (original, first used) is working in Kee again. I don’t mind if the second doesn’t work at the same time with the first (although it would be nice), but would like to be able to keep it open.

There are a couple of Kee settings in the “Finding entries” section which might explain this behaviour - they can be disabled to prevent Kee from searching or listing entries for anything other than the actively selected KeePass database.

I have them disabled and will see if this works. However I wonder very much why instead of searching all databases and showing all results it shows none when enabled.

Due to security reasons, I would prefer KeePass/KeePassRPC to have a list of database names, which are available for search/modification, rather then having to enter a name in a relatively volatile browser addon.
Another possibility would be a keepass database property which enables or disables the specific database being searched or modified.
Would any of the above be possible?
