The best thing about Google Flights is how fast it is. The +/- 3 days (or whatever) options are never really exactly what you want, and while Google Flights also doesn't let you execute really powerful searches, you can at least manually search at a rapid pace (<1 second per search rather than >10 seconds on other sites).
IshKebab, we really do work hard to make Flights fast (the amount of data we have to keep cached is pretty insane, IMHO!); thanks for the kind words!
re searches... it's our hope that -- for most folks and most cases -- our filters + our tips will suffice. But if there are specific power features you're looking for, let us know via the Feedback option and I'll do what I can to bribe, er, win over my teammates :p
