I really like this mod, but the only gripe I have about it is that it doesn't remove the version text:

Also, it would be really nice to have an option to center the title screen (move the title and buttons around with an x/y offset)

I'll look into the version text removal. "move the title and buttons around with an x/y offset" This already exists or am I missing something? Just go into the title screen options and there should be an xy offset there for you.

[Off topic] May I ask how and where did you get this panorama?
