Comment 30 for bug 691380

Yes and no - the new Quick Filter bar has a different logic but individual buttons for the search items which can be freely combined, and new criteria to search for which haven't been present in the 2.0/3.0 search options.

Thus, such a compact Quick Filter bar would need to compromise between limited space in the main toolbar and retaining the functionality. I could think of a drop-down menu similar to the folder-column selection, where you simply check all criteria that you want to apply and then hit return to let it run. That menu would only be needed if you want to change the selection.

That should be intuitive enough, but some ASCII-art mockup may indeed be useful to get a better idea what this could look like and how to arrange the items within the drop-down menu.
