It would be awesome if you could upload two photos for each switch to illustrate it in it's "on" and "off" state. At a glance, it'd be even easier to see which lamps are lit, if the Christmas tree is on, etc. without needing to look at the switch names and colors.
Ideal for me, as I'm quite severly colour-blind. Most on-off indicators are red/green. They are two colours I can't tell apart. 10% of males and slightly fewer females have a colour vision deficiency, and your suggestion would solve the problem for us.
I have to tell you though that through experience with communication with Belkin on these pages, nothing will happen.
