Started to use the beta version (with kerning groups) in photoshop, one thing that I have noticed is that after a certain number of groups have been applied in the panel, it suddenly goes really slow.
A little thing at the bottom of the window says “Refreshing font” but it takes about 5 seconds to do so. While it’s doing that you can’t do anything.
I’ve uploaded a very boring video to show what I’m talking about https://youtu.be/Y3kaFLoSmV4
It’s making adding kerning groups, very slow and painful as I have 4 for each letter.
