An option to quit or switch off the light on lens cover closed will be handy.
I was using the torch yesterday and automatically closed the lens cover.
An hour or so later I spotted the battery drain and light from the gap in the cover. Oops.

This is habit from using flashlight application TBH.
I am starting to use lanterne as a replacement for it.

FYI I have been having the issues with updates not coming through either.
I have been installing with terminal and apt-get.

Get root and "apt-get install lanterne --version 0.3.0" (or latest number)
