I really like ArtRage, and there's not much that I would change about it --though extra goodies are always fun . I do have one suggestion for the next version, though.

I would like the path to the Reference Photos to be saved in the file so that they are automatically opened the next time I open my work-in-progress. I will sometimes work on a piece across several days and now it's a minor annoyance to have to go browse and find my reference again each time I open my work.

Keep up the good work. It's a great piece of software!
