I just wanted to post a message to say how much I like this Glyphs app - I’ve been using it for a couple of hours so far, and I’m really impressed by the elegance and power of the interface, and appreciate how much care and thought has gone into every little nook and cranny. Terrific job! It’s so refreshing to me after using so many applications that don’t quite match up to a native macOS experience. 
While I’m here, to avoid wasting a message, here’s a question I found. If you paste a string like this:
"/tmp/filename.png"
into the window, only the quote gets shown. It might be the forward slash being escaped or something?
