A new feature need has surfaced suddenly.
I have this Mugen Power 2400 mAh battery now. Currently I still have their design flawed back cover, which is missing the critical magnet and microSD-card cannot be mounted. But after they have fixed it, it still will be reality that back cover won't have a lens cover, and the device thinks the lens cover is open all the time.

Now shortcutd obviously has some switch, that it won't work when the lens cover is open. Yes, that would be annoying when you are trying to take a photo, some shortcutd triggered action or usermenu would pop up. But now with this bigger 2400 Mugen battery, shortcutd is useless.

Shortcutd could still be used, optionally if user chooses in the configuration, this way:
Instead checking if the lens cover is being open or not, it would check if the camera application is on the foreground, "maximized" or not. (I'll create an "official" bugtracker ticket fot this later.)
