Since I answered the poll "No, I want moar functionality", let me explain my reasoning. I think this feature could go very well with eg TOHOLED, but I don't think I'd buy it if it was the only feature, even though it is a cool feature. I know it's hopeful thinking to add this to TOHKBD (by judging the response of dirkvl), but coupled with TOHOLED, I'd probably buy it.

I don't think it would even make the OLED Other Half any thicker, judging by the picture, and there would even be synergy between functionalities, with OLED having the capability to show what was toggled on/off (this probably needs community coding effort). That would be neat.
