1. I think it would be helpful to know the appox. width and height
each grouping would take up. Of course that's dependant on the frame
width and spacing inbetween each frame, but you could say something
like "This collection would take up approx. 6-9 feet on a wall."
2. A frame company I use (Excel) has software where you can see a
picture in the different frame samples on your computer screen.
There's a color picker where you can choose the background color for
the wall the frame will be on. It's totally not necessary, but could
be a neat feature to be able to choose your "wall" color.
3. It would be cool to be able to change the coloring of the pictures
to all black and white.
