Honestly, I think there should be some collaboration show by some professional people just to show a PROPER example to the shows. I'm not saying the shows in the navigation bar are bad, but I think a newbie might be too lazy to read them (just like how I never read them when I was new), so its better if he gets a single show to read to find out what to do and what not to do.
I also think the Video Game Layout needs some improvement. Yao Ming.
Ever considered making a Grey Matter floating template on the right or left side of the main page screen to welcome the users? It'll be fun.
I think someone should delete the rip-offs of the canon episodes on this wiki. What I mean with this, like when some Omniverse episode or something is announced of but not out yet, fans would go on and create pointless pages for the episodes will go out, which is just their imagination. I do not mean with this the episodes of a show that is, "a better version of EXAMPLESHOW", or "How EXAMPLESHOW Episode EXAMPLEEPISODENUMBER should happen", but the ones that the fans spammed with. I mean, the wiki is crawling with old "rip off" episodes that write false information about Ultimate Alien episodes who were new by the time the pages were made.
