I like the suggestions, particularly the third one, which I'll amend thusly:
-Increase searchable skills to at least 6 categories max instead of the current 4.
C'mon, players have 12 skills + exp + GS (the latter two not listed in the search filters), and we can search for at best 1/3 of a player's skills.
It's essentially the same TL search that existed in season 3, with a couple of features added for crap like potential, height and nationality. Oh, and advertisements.
