yes, I'm not sure why that is. I think the .deb needs to be in a different format for the app manager. I'll look into it.
just remember that to remove, you also need to use dpkg -r timelapse

In other news, I'm getting the hang of gstreamer and I already have a live preview, instead of static pics. So, no more gst-launch!
A couple of questions for the community:

1) do you think the camera should auto focus every shot or just once in the first one?
2) how the hell am I going to get all the controls for the camera (brightness, exposure and so on) in the ui? any ideas?
3) this also means that HDR pictures are going to be possible! need a mode switch button somewhere...

expect good things soon
