A lot of these options are already up and working over at xda. You just have to mix and match what your looking for (have a nandroid/backup ready...lol). Right now I have extened power menu, no longer have the Google search at the top of the home screens (and the space is usable and Google search still works).
I'm putting together a zip right now for battery percentages.
Home screens to auto rotate
five soft key button on the bottom: back, home, search, settings. I see mods that have this with setting on both sides but would look better if we could see them all the time.
A ROM that auto toggles between 4g and 3g (or even 4g to 1x) while the screen is off, and does it seamlessly, to conserve battery.
I scream! You scream! We all scream for ICE CREAM SANDWICH!
Most of you guys are searching for roms when you should be looking at apps. Half the things you want are solvable with them. And if not, just look at mods. Go on rootzwiki, they have a bunch of stuff.
More vibration (if that is even possible????)
Reboot options as everyone else mentioned
add widgets from homescreen (why did they take this feature out?)
Multiple scrolling docks built into native launcher
Anytime someone dares me to walk a mile in their shoes I do it! Because, hey free shoes and I am now a mile away from that person!
Hatred is by far the ugliest trait any human can possess (think about it)
