I found them very helpful too and my contact was with Eric as well.
We could just reskin it but I see a couple of problems (and they're not serious).
I assume the buttons have to be in the same place as there is no skin file showing position of buttons etc.
The dialer only has phone functionality. There is more functionality in the sdk (but it may not be useful)
It costs money!
Its not integrated well with RoadRunner (Personnal choice).
But mostly your right in that its not much fun. I've learn't an enourmous amount doing this when I'm not a coder by trade.
I'm looking forward to when they release the phonebook and sms stuff in qtr 2 and will be integrating it into this plugin.
I have a new version with caller id, incall and model / manufacturer labels but haven't released it yet as my chief tester is having trouble. Anyone brave enough to risk it can pm me and I'll send them the new version.
