there is no way to do this right now like the screenshot, but it introduces some interesting ideas about having a slider control in a list in the future.
I guess a way to fake it would be if I made a way to mark a field off as an "image" then it would read in the value of the field as the image you want to display. But you wouldn't be able to adjust it from the list view....and you would have to make an additional command to save the image field data.
if you could make it display the stars in the cat it would be great...
to be honest, i wasent expeting the slider style click, a simple toggle would be more than enuff (i am a remote control user so sliders are out for me anyway).
If you could show it in the cat and have a toggle stars function ( * - ***** and back to * ) it would be great.
