Bluetooth purpose? Just a switch to make it quicker to toggle on or off.
Thanks, I like the look personally, just wasn't sure it's anyone else's taste.

I know, it makes sense. I had to use text to match minimal size with maximal info, and provide better precision over more attractive formats that only suggest approximate values. They're wider to fit critical info, e.g. CPU usage is meaningless without knowing the frequency it is measured against or the CPU temperature and so on. Since they're separate skins and not a bar, anyone can load only a few of them that he deems necessary.
You sure did, along with your skins - will see how it'll turn out, I'll have to reconcile lots of possibilities and constraints (since I crammed more in them than you did).
I'll surely do.
