Valid point. buttonled_bright would be better on the Hijack menu. Perhaps just one value - buttonled_dim and have it be 0 or 1 for using or not using the (x+1)/2 method.

I hesitate using an offset like that. What happens if you put in a fixed offset, but change the bright value on the fly? You might run into a situation where your brightness becomes invalid.

Perhaps two Hijack menu options: one for bright, one for dim? Or, just one menu but have it detect and set based on the dimmer value.
