Dear friends,
I do not use any skin, but I do like to add few UX modules (like "Lego") to add some functions i like to program.

With almost all phones (and other navigation devices) displayed altitude is not correct. It almost always has some (fixed) offset specific for that device itself.
I know there is function for changing altitude offset in pongo skin, but...
As I don't want to use complete huge skin just for this function, do you know for any (or can make) UX for changing/applying altitude offset which could be used without skin (default skin)?
