good ideas -
and it's nice to hear that people are getting some use out of the program

i think a good alternative to trying to implement a multifont support would be to allow you to easily specify an "image" for cover page and back page; then you could simply make a custom picture with your own fonts and stuff in an image editor and use that. what do you think? or would that be too inconvenient?
as for supporting a directory of image files - another option is the "image to avi" freeware tool i linked to on the flipbook printer page; it will make an avi from images, which flipbook printer can then add.
as for single frame stepping, see the attached picture, there are controls for that.
i will try to fix the recent projects issue.
some more ideas i plan to add to next version in the coming weeks:
- more printing options like support for n-up and printing order options to make it easier to stack images for stapling.
- ability to add subtitles
ps.
if anyone has more card stock labels they have created please post them.
keep the ideas coming!
