Deleting pictures and full view

I find that although there is a nice full view app, I'm not able to view a full screen picture unless i start the slight show, in addition I'm not able to zoom in a picture unless I edit a picture. This is unacceptable for 50 Euro paid for the software.

Another annoying problem is deleting picture. If I mistakenly push the delete botton when I view the picture I cancel the pic from Iphoto (I know that the file still remains in the hard drive, but hoe will I remember that if I'm pushing the delete botton without awareness)

The software should always request to be sure to delete something.

Please apple, make something for make to software really good and not as average as it is now....
