This is great. I am
so glad this is getting done! I've spent way too much time clicking around the horrible distributor search engines, trying to determine which parts are cheap, readily available and will remain so (these three things usually go in hand). It is incredibly difficult and time-consuming if you are looking for something like a 12MHz SMD crystal: good luck sifting through thousands of options.
The current selection is very limited, but still useful for many projects, I will certainly make use of it.
The logical next step would be a KiCAD (and possibly Eagle?) library containing all the footprints. Not just thrown in there, or auto-converted, but actually verified by a human.
