Hello, I have assigned "<" to "filter fayt in order to make use of that, but it "synchronizes" with the Filter Bar and thus is of no use. It could however be extremely helpful if it were acting as a filter ON TOP of the Filter Bar filter results ("AND"). Perhaps you could consider this?
There’s only one quick filter. No real reason to use both methods of changing it at once. Pick one or the other.
If you need multiple layers of filtering, that can be done via other filters. (Folder options, via the select menu/command, or find files, giving up to four layers of filtering, as well as the options of compound wildcards and complex filters at each level.)
