[Graphics][Features] Shortcuts for formatting and Themes

Shortcuts would be really helpful when making a long text post.

The thing about not having a mostly utilitarian black/white color pallet like Reddit is that the design can get old after a while. I feel like a theme engine would make this problem go away.

Edit: Ok so found my biggest gripe. The front page is more like /r/all, instead of my interests.

Also where is the option to see past posts?

Edit 2: Also where do comments go to? I don't see them as messages.
