I think many people would benefit from ability to Group accounts in a Vault to a particular Group. Then, maybe list the Groups at top (or have a setting to where it might sort within vault same as account), or think of the many ways to sort / show them. But, point is that the Group will subsume the Accounts and hide them until I double-click on that Group.

Let me give an example. I want to create a Vault called, "Eat Out Accounts". Well, I need to move all of our Whataburger, Wendy's, McDonald's, Subway, etc., accounts there. But, each member of family has one, right?

Well, be nice to group all McDonald's accounts for 5 family members, under "McDonald's Groups". Then, double-click and it shows 5 (or more) of them there. Because they're gonna be named, "Mcdonalds -- wife", "McDonalds -- me", etc.

Then, it would be so much easier to re-organize them from Lastpass into a simple structure, which now -- with ProtonPass, is like 250+ different eat out accounts in huge list. But, it doesn't really need to be listed like that. And, it doesn't make sense to have a single vault for "McDonald's accounts" ... right?
