Hello there!
This plugin is a HUD designer plugin, used for creating HUD elements. HUD elements are values that always appear on screen that reflect to certain things like character value, variables, etc. It's not for creating game menu like Inventory Menu or Equipment Menu.
HUD fade out will be implemented in the future. And yes, you can be sure I'll help you cuz I'm online nearly 24/7. Although I do suggest joining my Discord (link in the front page) because I'll respond at much faster rate there.
