Yes I understand it way better than before because of the refactoring. Im still more a beginner when it comes to coding but it motivates a lot if the main work is done so Im very enthusiastic about your toolkit. With input I meant the keybindings, I only got my inventory opening when I put it into the BP-Playercontroller. What makes sense though. I using a youtube tutorial for that but its for a thirdperson-character. So I need to rethink parts of it. basically I want the unit in a collison area around an item and when the mouse hovers over the object it starts to highlight the item then click on it and it goes into the inventory. Maybe I look into some documentation about the things you mentioned so I find something to solve it. I also started the inventory thing yesterday, so I probably asked to early. sorry about that.
