Here is a neat tool that helps to speed up the task of flashing custom mods and roms. Obviously you can flash zips in Clockworkmod recovery, but some devices do not have touch recoveries and it can be pretty annoying navigating through folders especially if your sdcard is full of folders and files. ZipInstaller allows you to find the zips you want to install, que them up, then start the flashing all while booted in your OS so that you don't miss a beat. This kind of reminds me of goomanager, but it does work with ClockWorkMod Recovery. So far this works on a few devices. Galaxy S II, Galaxy S III, and Galaxy Note.
