Using finance as my example.

Currently as it stands, I can have a vault for Finance, it would include items such as Notes, Card, Login, Other... For one bank. Add multiple banks, and you get a very cluttered vault, very quickly, mixed with Notes, Logins, Cards that all say something similar. If you add other categories to the mix, the clutter expands.

In my case, I would like the ability to create a vault that just houses my Logins, but has the ability to link the logins to my Notes, Cards, Identity, or Other for that particular bank's login that is located in another vault or just in the default All Items vault.

This would mean, if I am attempting to login to my bank, I can easily from my login information navigate to the Notes, Card, or Other items for that bank, without having to hunt for it. And of course, if a login can be linked to a note, when the link occurs, if I am on the note I should be able to navigate back to the login, or whatever items it is linked to.

I think this would go a long way with making vaults be primarily for Logins, then use the logins as a means to link to additional notes and items.

Side note... The login with Proton for ideas. Doesn't work. :)
