Top Ten Things That Should Be In Super Mario Maker

Thelegendaries101 OK, so here's the problem: What if people tried to team up, making nothing but a tiny level with 3 Star Coins in a row? These levels could be posted everywhere to the point where there are at least 50 you can get. These levels are the creators gaining multiple star coins in order to achieve costumes as quick as possible. So, if they did this nonstop until they had to do something or slept, it would probably take them only a couple days to get every costume. And here's a question: Are you still sticking with the Star Coin shop thing? If so, what will you do to stop creators getting thousands of star coins?
I mean, we have red coins, but Star Coins could indeed be separate!
What if they only worked in 100 Mario challenge expert mode.
Love star coins
Something simple like a SMB3 style world map would be great.
This would be amazing!
That would be cool
That sounds awesome. Then you could play Mario in 3D from 8-bit to modern era!
Super mario 64 anyone?
This would be very complex and I don't think it would turn out as good as people think it would
Like say,super Mario Galaxy series style. Super Mario 64 game style. Super Mario sunshine game style.
I know that you're talking about the poison mushroom from Super Mario Bros. The Lost Levels. It's a great idea to add this to Super Mario Maker because there should be a touch to The Lost Levels.

Or change the world to earth.
I wish they made towers
We can make slopes but there can be a easier way added.
Bowser and his weak son aren't enough.
Maybe the Koopa lings, peaty piranha, king boo, and bullies would be great in super Mario maker
The Super Mario Land trilogy (especially Super Mario Land 2) is universally underrated, like many retro Mario games that lack anti-feminism. :(
Thelegendaries101 Yeah, I posted this one, and I agree. Impossible levels suck. I just thought if the level was obviously possible but the creator couldn't beat it, then it could still be uploaded. And I forgot to mention impossible levels would be banned. The reason I added this is to end developer exits.
(No offense to Nintendo) I hate having to beat a level in order to upload it, but I guess it makes sense. I mean, I'm pretty sure most of you would like to instantly upload a level, but who likes impossible courses?!

It's the best item

Being able to pick up switches should be an option.
