Change size and position for X- and OK-Button?

[Minipli]

Hi,
using great Artemis Touch 3.01 ROM I was just wondering how to change size and/or postion of x-and ok-button (top, on the right). Sometimes I have problems with my "big" fingers to press these buttons so it was great if you could change size or position of these buttons. Is there allready a "solution" for this?
Regards

Use the OK-button instead?

Yes, still using this but I want it reachable on the touchscreen. On HTC Touch devices you don't have an extra ok button for example.
