I should have quoted "blk02si", as it was his post I was "replying" to... I've tried many front ends, and touchscreen volume control can be problematic (at least with my lilliput). Media car was slow, frodo was fast, last time I tried road runner, it was slow... all on my 1ghz class machine.
What I meant was, it's a good idea to have an actual volume knob instead of relying solely on a skins or front ends touchscreen volume control. You can expound that to using hard buttons for the 4 or 5 things you want to do (mp3/gps/phone/obd/etc), so the skins menu navigation system doesn't have to be used.
If you had a few programmable hard buttons, a skin developer could worry less about filling the screen with cluttered stuff, just to navigate between the functions. It wasn't advice on how to make the skin better (I love it), it was advice in general.
