Thanks for the praise!
Voltage/Voltage graphs are definately possible and the etch-a-sketch idea is a really cool aplication! Currently the x-axis is time-only but I could make it adjustable when I get back. I might just have to make me an etchasketch!
The rotate images work in MDX but cannot be configured in the Configurator yet. I cant access any of my skin files on my phone but go here: http://www.fusioncontrolcentre.com/MDX/Source/
In one of the earlier versions there is a gtr inspired skin that is ina folder in the MDX source directory or maybe the bin/debug area with the name of gtr or str or something like that. If you cant find it I will see if Tim has a copy he can post up.
As for the ports, I am still upgrading the Configuratorto access the new features of Version 4. You can do it manually in the Configuration file or use the ninja kitty wizard.
I am currently on vacation and laptop-less and I cant do everything on my phone. I will be back next week to answer more questions.
