Hey, don't destroy it yet, give it a week, it's a good layout!
To remap keys it's easy, for example to make your Delete button do shift, the steps are:
You can remap multiple keys in a single session, just hit "source key" (to copy a function from) followed by "destination key" (to copy the function to), then another source key, then another destination key, etc, and when you're all done, hit program+F12. Note, the source key always copies the original function of the key (it doesn't matter if it has been remapped). After you remap you Delete button to shift for instance, you can still assign the Delete function to say the capslock key by pushing Delete, then capslock.
It's a VERY nifty controller, best I've ever seen.
Oh, to bring a remapped key to its original state, just push it twice during remap mode:
HTH, and congratulations!
