At the moment you don't only need to enter the side bar > my stuff > scenarios
but also you need to open the editor of that scenario just to pay it. On top of that the play button is very close to the delete button.
So the problems are:
-you unnecessaryly open the editor
-Play button is close to delete
-your scenarios aren't accessible from the new game menue
Give your scenarios an edit and a play button, edit brings to editor, play starts it immediately.
Or better, put "own scenarios" button under featured scenario and from her you can launch the scenarios directly.
I think this suggestion is low priority but really easy to implement.
