Some Ideas

One idea that would be cool is a map filter. The map can get crowded really fast, so having a filter for the different challenges, players online/friends or fast travels would be cool.

 I noticed that during certain challenges, sometimes the specific things to do don't check off when you actually complete them until the challenge is completed. This made it really confusing and frustrating for me because even though I did complete that specific thing, it didn't check off until I was done. I restarted a ton of times on one because of this.

Saw this already, but having clothing and skateboard "Loadout" slots would be cool. Just a quick button press and I've got a whole outfit and board preset equipped.
