Since I noticed this software I am testing it and it works great. It is a taskmanager, yes, yet another one:)
As you can see in the above how you can use the taskmanager. Except for being a taskmanager it can also show the battery level (in %) or free memory (in %) in the topbar, time (local, Zodiac or GMT (OR not AND))
It works on WM2003SE and WM5.0 VGA and QVGA/landscape, and use a small amount of memory.
And best of all it is free
