Hello

Which Windows 7 bugs do you mean?
"Enable window colorization on the Classic themes": I already tried this, but without having success. Maybe I get this working some days, but I can't promise.
The battery on the desktop is called Sidebar Overlay, and you can disable it in the configuration:

The cursor... Something like this?

To get the remaining time if your system (not windows, this is a hardware related problem) does not supports it is not really possible. Any values can only be guessed then, because the power drain may be different at any time. For example if I use my laptop only for surfing I have about 3 hours of battery runtime, but if I'm playing a game only 1. If the battery remaining time is missing mostly the power drain information is missing, too.
(some of this settings are applied only after you restart BattCursor)
