Hedgecore just use Konttori's ThemeMaker 0.85, works awesome. Copy a stock maemo theme off your 770 (usr/share/themes) then browse through the files and use a graphics app to copy and paste those onto the nuvothemeSourceImage.png, Biggest problem is this would proly take around 6-8 hours tinkering for someone new to the app to figure out how to use it. ThemeMakers basic settings, as in what you see when you open the nuvothemeSourceImage.png is konttori's nuvo theme not a stock maemo theme so it may be hard for a newcomer to figure out what element in the image to change to get the desired results you want. It's trial and error trying to figure out what to change. One of these days i will do a full tutorial on how to use ThemeMaker.
Quick how to use Thememaker:
download ThemeMaker from https://garage.maemo.org/projects/thememaker
in the Thememaker folder open nuvothemeSourceImage.png in a Graphics app like photoshop or gimp that can do .png files.
nuvothemeSourceImage.png is an image that has 90% of all of a themes images on one image file(there are over 500 ideviduale images that make up a theme).
You edit parts of the picture in between red cut marks to display as you like.
Take care to notice transparency around edges of certain parts of the theme.
After editing the image save it as a .png file.
make sure you save it to the same location inside thememaker folder as nuvothemeSourceImage.png.
Run the MaemoThemeMaker.jar app.
Name your theme and select a font size (Personally i like 16.75 for system font and 32 for large font which is the thumb keyboard font).
then select build theme.
After building is complete you will find a .deb file with the theme name you chose.
Copy that to your 770 and use application manager to install it.
You can try My AquaOS theme at http://web.mac.com/sonicjunki/iWeb/770/770.html to see what iv done using ThemeMaker. Konttori has done allot of work to ensure this app works as it should, he really has been great at taking all the recommendations i made along the way into account to make this app WORK! Tinting a theme just seems so lame to me but hats off for the effort.
