Suggestion: Better Search Filters & Search

I love the new Version 8 of 1Password!
But the Search needs to get better and I have a small Suggestion for that.

Search Filter:
We can already use the Filters like =kategorie:Logins =tresor:Business when you press STRG + F.
I would prefer it if we could use some "Shortcuts" to simplify the Search Filters.

If you could also improve the look of the Search Filters like suggested from @ag_Gabriele in this http://https://1password.community/discussion/comment/615142#Comment_615142 then the search would be so much better.

Searching for Parts of Names:
A lot of people on this forum have already asked for this. The search needs to have a possibility to search for parts of the names.
Example: *key = Searches for everything that contains key like keyfinder, yubikey, or Door Key

Searching for Untagged Items
As requested before (https://1password.community/discussion/124505/search-for-untagged-items) it would help if we could search for untagged items. I'm currently reorganizing my tags and this would speed up the process.
