home screen UI changes

I don't think it's super necessary to have 2 different menus (one in top left, one that slides out from middle left). Keeping the top left one would probably be a good decision and maybe adding some tabs that are frequented (eg. home, search, community, etc.) to the header would clean things up a little more.

Also, the main home screen looks like everything is kind of squished to the side, probably because of the anime ranking thing. If we had a horizontal ranking system instead it would save a bit more space and also allow the anime categories to widen up a little bit. Maybe adding a carousel thing where arrows can cycle through titles will clean things up a little more as well.
