Forgive me if this sounds dumb but I found your tool via highqualitygifs on reddit, and being pretty naive regarding after effects I could not for the life of me figure out to make it work with either AF CS6 or 2019.
My base assumption was that (after adding it successfully to my plugins) it was preset for a default optimization without changing any of the options, which causes nothing to happen. That caused me to waste several hours of fruitless sleuthing to figure out what step I'd done wrong only to find out by accident that I have to mess with the options to actually get it to work.
Please clarify this in the read-me and the web page for idiots like myself!! haha
