I include Doggie so that people have an ICS-themed file explorer app already there, without the need to download one each time they flash my ROM. Saves a bit of data usage, and a lot of time, if you have 99% of the apps you always use, already on your SD card. That way you can just go in with Doggie, and install every app you want, no delay, including whatever file manager you use. When your ready, just use your file manager if choice and delete Doggie from /system/app/.
Also, you have video playback? How? Doesn't even work for me. I know face detect and all don't work, but video camera and video playback works?
