@SilentNL: If you want to get technical, most of the things he posted are simple edits or already released somewhere.
He didn't specifically mention it, but the 'wearing wings all the time' thing only took me about 5-6 hours spread over a couple days to get working. Although I am decently skilled at C++, my skill only aided in understanding how the original wing stuff worked. The actual edits I made were very simple.
The old + new glows, as you said, probably just removing an #else somewhere.
An old version of Arena Score is already released, but since the screenshot is very generic, we have no idea what's new in his 'Version 4'.
The Guild Maps is basically a copy of Guild Houses, but it sends you to a different world (if you don't mind replacing old guild houses, you can send them to a different map by simply changing 1 thing in the source...)
I don't know if he did this, but the Quick Jobchange he showed in his post could easily be Pumbaaa's Job Changer (already released) with the window design completely changed. No matter who made the Jobchange though, both versions could easily look the same if the window is changed.
The Toggle System is just some /disguise commands put into the window (and maybe a little extra coding to make the wings show also).
The Colosseum (I have no idea who made the original) is already released, and that screenshot doesn't show enough to prove that it's different.
That's all I can say about them. The things I haven't mentioned, are actually original from what I've seen before. (I've seen different colored glows, but I didn't know the color was created dynamically in the window).
