Updated (see first post).

Fixed
- no "lenscover screen" in transition to the preview window.
- zoom key z/Z updates zoom slider
- switch back from frontcamera to backcamera when scene mode
changed to image capture mode.
- recorded videos are now in "recorded from device" category
- start image viewer/mediaplayer button in preview window
opens the image viewer/mediaplayer with the last taken image/video
(in the prior version the image viewer/ mediaplayer was just opened)
- preview window closes after deleting the image/video

Thank you for your feedback!
