Filtering on all columns would be very helpful, especially if saveable into filter sets, like in excel, but retaining regular expressions like existing filtering
You can use Tools > Find Files > Advanced to filter on most column types.
Yeah, but 1.) that's not convenient, and 2.) that's a different use-case.
I can't speak for the OP, but I would give my right arm to be able to filter on at least the Description field, too. It's not a matter of finding files but of hiding non-matching files in the current view.
You've understood how useful filtering directly and dynamically in the file-list view can be, not having to execute searches and possibly save those in a collection. I've also figured out how to break description into subfields to add multi-category classifications to files, but once I have that, all i can do is group and sort, I can't filter, such a pity.
Many tools support this now, not just excel, and they're often defect management tools, e.g. the industry standard ALM took, HP's Quality Centre.
You're correct in using a search to do this, but that doesn't give the ease of use of direct filtering.
A: Are you suggesting that you're thinking, of also delivering a feature, like an MS-Outlook search folder, which gives, in a collection, a dynamic filtered view based on a find/search expression?
That would also be useful, especially if it had a snapshot feature so that earlier search-result-sets could be preserved, e.g. by as set of as-of- subfolders
B: If flatview could be delivered to collections, that would also be hugely helpful, especially in the context of 2. A immediately above
