Amazing app which perfectly fits to the 4Ext Recovery!
I really like the features the app provides. One of my most favorite feature is to make a task in the app which does several things with on reboot. E.g. backup rom, full wipe, install new rom, install new kernel with just one reboot. Amazing
It also lets check you MD5 checksums before installing zips, no extra app needed any more

I recommend this app to everyone who uses 4Ext recovery and everybody else, too ;)
