It has been discussed before but I can’t find a place that summerize my take on it:
1- Would be nice to have an “apply” button to avoid going back and forth when testing.
2- A scroll bar: with hundreds of fonts it takes ages to go to bottom.
3- A preview in the name of the font, like we see in many text editors. With the option to turn it off in prefs because it can be tedious with music fonts…
