The "second quest tab" is the achievement tab, just an FYI.
No offence but I don't really see a use for any of these except maybe the donor box, the owner icon, and the achievement icon.
No one would use the scrollbar because they need the rest of the sprites. It'd be kind of funky to have one part of it green and the rest blue.
I also don't know what you edited for the mod icon, as I didn't see any changes.
