I used to do a lot of scripting in AE about 5 years ago but took a break to work on more advanced applications build in python. I'm coming back to Extendscript to work on a few new projects and I notice that in the last few years scripted GUIs are looking MUCH nicer than what I used to do, however I can't tell how people are doing them. Browsing aescripts.com I see a lot of beautiful work out there.
Does anyone know what these guys are using to create these highly customized and interactive GUIs? Do I really just need to up my extendscript game or did something new happen in the last few years?
