strongly support the three ideas (# 16, 14, 12) to a very nice and useful application.

Comments:

#16: Installation - registration - buying is confusing unless the "buy" button is removed and a "registered" label is displayed.

#14: Editing is too low level, e.g. I lost an edited background and had to re-start the operation.

#12: Capturing/zooming/etc as described by the previous user would be a very nice and useful function.

Congratulations for a quite well designed applicaton. We'll help you to enhance it.
