Simple plugin that changes the engine's default behavior regarding sealed skills, making them hidden instead of just greyed out. Undoing the seal works as normal and shows the skill again.
Reason for making this: I couldn't find a way to hide skills globally without notetags everywhere, and needed this specific function for a personal project. Figured I would share it.
Free for use in any project. Enjoy!
