Omg thank you for letting us know!
I've been on the free trial just waiting for the summer sale to buy EX!
it has sooo many great features for making comics, although it was really the asset library and converting 3D objects to lineart that really won me over since I needed more tools to save time on my comic.
For anyone who's still on the fence with clip studio, there's a 3 months free trial and when that runs out you can get an additional 3 months free trial if you sign up for the monthly plan, the first 3 months are free so it won't charge you until the trial is over, you can cancel before then.
