Nice one, I see you got the sliders working, and they look quite neat! The up & Down buttons take up a lot of real estate, and it may be an idea to add them like a normal windows slider bar in between the display and the number pad buttons. That way the display could be longer, to get a couple more lines in.
Th Battery symbol seems to be not quite right ! This is a pain to change as well, as it is in 20 files.
How does the UI work for you ? The font is good and stands out well against the skin.
Play around with the skin as much as you want. I am not precious about ownership of these things. I believe in Open Source, and sharing ideas to support the whole community.
I have ordered a new laptop which will be coming with bluetooth, so I can test this out myself then. I might even add a BVOA Phoco skin with the same UI if it works ok. I don't know much about Phoco at the moment.
Keep up the good work m8.
