Now that I have had some time to look at things here is a concept for the new PHIDGET HOMEPAGE!
There is 1 central screen that will take you to the relays, sensors, or a setup menu.
The relay page is the same as before, the sensor page can display raw data from the sensors or possibly interpreted data (such as mpg).
The setup menu is the brains of homepage. This is where everything is configured. You will be able to select the kind and purpose of each sensor, additionally you will be able to select different "background tasks" such as data to be displayed on an LCD, volume controll using the encoder (there is a thread about this in hardware dev.), controlling headlights at specific times (or using a light sensor), a basic security system or any other software interaction with phidgets.
The greatest part is that hopefully it will receive all the programs for its sensor data and background tasks from external modular plugins (plugins within the plugin!). This will make it easy to update and it will open up the floor for more ideas and possibly more developers.
This is an interface for cars however the setup menu is designed to be used with a mouse and possibly keyboard, if you feel some changes may make this more touchscreen friendly let me know.
Also, users may not want to always scroll through the plugin page in amp and then the homepage as well so phidget touch buttons could be configured as a background task to immediatly call the relay or sensor page.
Many of these concepts actually come from the first frontend that I ever saw for mac Tatraapp by Jirka. Also many thanks to Aychamo for amp and a great interface to start from
