1. In pass everything is encrypted but you have to give names to each gpg encrypted password file.

2. Right. I use rofi-pass on Linux which fills in the selected password or other login data without any clipboard action.

3. True. Never thought about this but sounds clever.

4. Same answer as in 2.

Plus I have a good password history through the git commits. Of course I push it just in my local network.

And I use more then just one password store. And inside you can folder based decide who can decrypt the passwords and who not.
