This just clicked in my head....
The R&CF:ToD Theme had custom sounds too...
Have you found out a way to put in custom sounds yet?
(Its also in the 2 PAIN themes as well. -I love the cookie theme *slap* Oh yeah!-)
Maybe you guys could decide what sound goes where...
(I was thinking every time you switch between menu items it should be a revolver wheel click. Selecting messages should be the revolver shooting. And going back out of the menu item should be a bullet hitting someone. When a download finishes, or when an alert comes up it should be the voice from Metal Gear Awsome saying "Awsome!")
Just an idea... Look onto that in the future yeah?
