Don,
I see your point: the 'canvas' for ccf in prontoedit is only 240*320: this means that if you double the size of your buttons to make them look better in vga, you will also have to deal with the fact that this means less buttons on the canvas. The file-size is no problem: memory on PPC is ever increasing. And no: you probably can't use vga ccf in pronto, but I am only interested in TR and pocket PC's. But still nice of you Don to be so considerate about other companies ;).
But: vga is the next thing on pocket pc's: Toshiba e800 is the first, the rest will follow. This might become a problem: does native TR look good on vga? Ccf will probably become unworkable on vga. Are there owners of a Toshiba e800 that use TR in vga mode?
