I believe there was a plugin by @Mark that showed a user-selected set of fonts displaying the current string, but I can’t find it anymore, is it not available anymore?
@mawns it was likely my Font Spy plugin, which was available for Glyphs 2. I am about to get it live for Glyphs 3 very soon.
It is incredibly useful and really a great tool, I can admit. I use it a lot and want others to know of its usefulness as well.
One issue I had with it was the hardness of promoting that usefulness properly. I had only a hand full of (really happy) users. Everyone who has it, doesn’t want to miss it. But it was hard to maintain the work on it with so few fans of it.
Anyhow, the Glyphs 3 version is already in use here and just needs a tiny more work to be public again. I hope to remember this thread to notify you in hopefully a week or 2 when it’s live again.
