This is an awesome idea with a couple minor usability hiccups.
Obviously this makes finding fonts much less painful, but the number of times I need to do this makes it hard to justify giving it permanent screen space at the top of the editor. Is there any chance this could be optionally relocated to the Project > Tools menu? (I can probably put together a pull request if you’re interested)
My other concern is that I’m sure sure Google Fonts has a lot of fonts. Are there any plans to add search, filters, or sorting?
