  • Ranged item mod elements from old workspaces will be automatically converted to projectile and item mod element pairs

Brilliant update, shields are a huge deal, I haven't been modding a lot lately but I may start back up. 😀


I would gladly to improve the "Custom Element" so you can change the path of that "Custom Element" you want to create. That would be really cool, so you don't need to stick it to the root Mod Folder.

Will there be anchor points in custom gui, not just overlay?
