GDevelop spotted improvements

Hello Muzan,
Good to see you back.
I see that you’re mostly opening a discussion for your points, so as stated on ⭐ Welcome to the User Feedback channel!, I will not tag this since it is not a single request (btw, I think that some topics already exist for the things you are requesting so feel free to give them a like).
I will also move it to General so it can follow its free multiple demand flow.
