A "ding" to play when the lighting finishes rebuilding.

Pretty self explanatory, just rebuilding lighting can take a bit of time, so I think it would be nice to let the user know when it is done through some kind of audio cue, that way I don’t have to just sit watching it go from 0 to 100. Or just so that a person does not need to keep checking up on it to see if it is done, you would simply hear that it is done.
