I've made a MMTaskManager skin. This is the one that's included in R3 ROMs and will be included in all future versions as I like it much better than the standard MMTaskManager skin. The "X" close button is from NinjaDucks' Simple Gloss Arkswitch Theme. As usual you will be able to uninstall mine and install your own if you don't like it.
I've made a cab for anyone who likes it but doesn't want to flash an R3 ROM.
Here are a couple of screenies. The memory % is a little hard to read, but it doesn't bother me because I don't often use that info.
I can't try out the cab because my ROM already has this skin in it. I'm fairly certain that it will work properly, but if someone can try it out and let me know that it installs and uninstalls properly, that'd be great. Thanks!
