I made a post about this ~1 month ago, but this was never added. It got a response, but yeah.
This addon is a gui addon for skript. It is a fork of TuSKe that is actually being updated. We are going to start needing this addon soon as TuSKe is super outdated.

Note: I would recommend keeping TuSKe still! Some of the syntax has changed in this fork!
