Same here. Bit annoying, as I'd like Shortcutd to still work with half-presses when lens cover is open. Would be great if all of these things were configurable.
Also, nicolai - any chance, but the time this is formally released, you could make your camera-ui2 package get installed as camera-ui (backing up original, if camera-ui can't be reinstalled at uninstall), and use the same DBus interface(s)? It would certainly make it more of a proper "replacement" for the closed camera-ui we have, as it would just snugly plug in to the gap left by the stock one. Also means cl-launcher and the like don't have to be recoded to check for, and use, camera-ui2 specifically.
Also, I would suggest that your camera-ui2 load, and save, the same gconf settings camera-ui uses. That way the transition is even more seemless, less stuff breaks, etc.
Also, please include, whenever you get around to this, some way of chosing whether the camera opens in camera or video camera mode. (There's already suggestions for this, of course, but I really wanted to stress that. Some of us only use the stock video camera to take video, and let the other camera programs take care of photography.) Even something like it opening in whatever mode of the two it was in when closed would probably be welcome.
