I would love to see a toggleable feature that displayed a left to right scrollable map list (screenshots), located under a users sig in their posts. I used to like seeing peoples maps listed in their sig but two problems occurred. 1) the sigs got monstrous or 2) people typically would only show a couple of their maps. Sure you can search a profile and check their maps, which is awesome, but a little bit of advertising can help promote a map that may have gotten overlooked. I don't want it to get spammy, just a small slender bar at the bottom of the sig. If you can hover over the image to enlarge it in that OSX'y sort of way, all the better. Here's an example:
The Squally DaBeanz map factory would probably need two or three bars by the time Halo 6 rolled around XD I kid, I kid
