This issue with the fonts seriously needs to be fixed. I've used your products for almost 10 years and have never been so frustrated in my life. All I want to do is start typing a font name and it jump down to that. Do you know how many fonts I have after TEN YEARS of design work?? Thousands! Now instead of spending my time actually working on projects, I'm trying to find a solution to this problem that shouldn't even exist. Put it back the way it was!
