I had some free time at work, so I decided to play around a little with the developer interface for SD.
Before I knew it, I was on my way to making a Mazda skin.
Here's what I've got so far:
I like things plain, as OE as possible, so I reorganized the home screen, took the clock off as we have the clock in the dash anyway, and then rearranged the keyboard to qwerty.
When I get more time, I'll go a little more in-depth and learn some more.
It's really not so hard once you get the hang of it :)
Comments and suggestions would be much appreciated!
P.S. in the car, it's red to match the dash, but for some reason, I can't change the colours in dev. mode, so if you install it, just go to settings and change the colours to match the dash.
