Password becomes Login

While 1Password does not use a folder structure, adding all of your items to the personal or shared vaults and sorting by category, and organizing with favorites/tags is your best bet.

I like 1Password but "folders" are better than "categories".

It's possible that I haven't learned how to properly handle 1P or the idea behind categories and tags yet, but somehow it's easier for me to imagine a division into folders (which accompany us in many aspects of life) than into categories and tags. I just miss at least one more level of nesting.
For example:
Level 1 - Vault - Division into clients
Level 2 - Categories - Data type division (IMHO 1Password works best with its own categories if the data types are large to find passwords as quickly as possible).
I miss a level between 1 and 2 here, so as to add a "folder" grouping e.g. all devices of the "printer" type.

In the model you propose, I do not know how to use Collections.

Tags would be better if you could select several (but more on that below) and not just one, then I can achieve:
Level 1 - Vault - Division into clients
Level 2 - Categories - Breakdown by data type - e.g. own type: Servers
I can additionally filter with tags:
- tag: NAS - device type
- tag: Server room office - location
I have 3 devices left

It's hard for me to switch to the way of thinking proposed by all popular password storage programs, but I try. Own templates for Categories saved 1Password from being deleted from my list :)

Tags - preferably, if they work on the principle that after clicking on:
- All Items - shows all tags from all Items
- Collections - available in elements belonging to a given collection
- Vaults - shows only tags available in this Vaults
- Categories - shows only tags available in these Categories
Everything is done on the basis of inheritance from a given Item, which is in a given Category and Vault or Collection

At the moment I click on a given Tag and it shows ALL items from ALL Vaults. How is this going to make my search easier? How to click through and show all items that have a given Tag, are in a given Category and are in a given Vault?

It was supposed to be short and turned out to be very long.
