You may remember our recent article on how to compile Android 4.0 from source. Whether you’re already a dab hand at the process or you’ve just successfully compiled your first build, XDA Senior Member evilisto has written tutorials for a couple of very useful modifications that you may wish to incorporate into future versions of your ROM.
The first is a modification which allows for the remapping of a devices physical button to access the recently used apps dialogue. For instance, replacing a search key with the ability to view your currently running apps instantly. The second allows you to either alter or add to, the shortcuts in the notification tray. So as well as being able to jump straight to the settings, you could also easily access the recent apps or search options.
It’s important to mention that these modifications cannot simply be added into an already compiled ROM, they require changes to the code so a little knowledge of Java would certainly make this easier. That said, all the required changes are clearly outlined in the tutorials. The developer states that these tweaks have been tested on a Nexus S but should in theory work for most devices. So if you are compiling your own versions of Ice Cream Sandwich, why not give these a try._________
