I've been thinking about something similar as it's sometimes hard to update snapping when new LDraw libraries are released (this is also mainly why I added searching on the history lines to the part bin filter).
Maybe something like keeping track of the files I manually inspected (through a cfg file in de shadow lib) and deemed 'snap complete', those could then have some indication in the bin unless the part's history date is newer then the cfg file (so I'm forced to recheck them).
I like the dots idea to also indicated partial inherited info (without certification etc). I'll try to add it to 1.5.
