I think taht for FR2 theer should be a test button that you can't save your map until you have completed it once because some people just make impossible ones so I think taht you should have to test your maps to complete them( and you must but a goal in each level at least one) Who agrees with me?
Well it would be helpful but some people like to end their maps with no ending more of a continuos map of circles and stuff. I think it would not be needed although it could be of some help for people who like trying out maps.
Well this is a good idea, but I think if you want to implement it you should talk to the game creator. I don't think the mods/admins can change the games on the site. But I do agree with your idea.
