Chrome for Action Menu is available in the BigBoss repository of Cydia, and can be downloaded for free. In terms of dependencies, since it requires Action Menu to work properly, the tweak will automatically grab the required package if not already available on your system. Upon installation, the tweak does not add any Settings app menu of its own, nor does it sport a Springboard icon. What it will do, however, is add a “Chrome” toggle to Action Menu’s settings in Extensions, and toggling that on will enable the Chrome item in action menu throughout the device.
The tweak is certainly a useful addition to all the Chrome improvements available in Cydia, and the fact that it makes it easy to do something that would otherwise require some manual effort, makes it all the more useful.
