This is actually a very good suggestion! Will save tons of time. Personally, to decide what font I'd like to use, I open Google Fonts, enter my letter (e.g. F), and then scroll down the list of fonts to pick my desire one.

I like you suggestion very much, I'll add this to my suggestion list and would implement this one for version 2.0.

Thank you.

Further to this feature and the current dropdown, fonts which do not contain the glyphs in question should be removed from the presented subset.

That's right. I'll populate the dropdown with all fonts that coming from Google Fonts API. I'll add this to my todo list.
