When using the 'Filter vault items' list I only have the option to select a single category such as 'Logins', 'Aliases'... etc or 'All' which is everything.

However what if I want to search 'Logins' & 'Aliases' but exclude everything else?

I propose you remove the 'All' category and turn the 'Filter vault items' list into a multi-selection list.

Categories that are selected are searched (as indicated by the tick) and categories that aren't selected (no tick mark) are not searched.
