I want someone to become inventive and turn a simple tablet, like the Kindle Fire or equiv, into a light controller for my Quantum Qflashes.. basically to emulate sync with the Pilot and allow a touch screen control panel for any number of Qflashes.. where you can set groups, power levels, mode, on/off.. and where you can store light setups and drag around a top down view setup of the lights.. Place the subject, drag a light behind the subject, drag another in front and to the right, another to the left and low, etc, etc.. so you could then choose a lighting setup, enter the length of the set, and have the lights self-adjust to your predetermined settings.
If they feel ambitious.. I'd like a Android version of DSLR Remote, Helicon Focus, and a depth of field calculator with a graphic representation to go with it. More, add some model release and other common forms which can be signed by a stylus and signed forms stored on the device to be uploaded later.
Oh.. add a PDF reader so all your equipment manuals are available and a RAW viewer..
