Customization isn't really big here in PMC. Okay, yes, with the Sidebar update we can now set custom statuses, and we can also customize our profile to our liking using widgets, changing your profile image and banner, as well as activating pets, but that's not enough. So, here's what I'm thinking:

1. Custom XP bar color
   We're stuck with the classic Green, as well as the orange during October, but some people would really enjoy that little touch of personality by being able to change their XP bars to whatever colour they want, whether it's yellow (which I would greatly love), red, orange, green, blue, cyan, purple or whatever, having that extra burst of colour would be nice. Oh, and while we're on the topic of the XP bar...
2. Light Blue or Red and Green XP bar during the holiday season
   We get an orange bar during October, so why does the holiday season get left out?
