Two more bright ideas here.
1. When you choose your city/location, etc. in the stationary pad it would seem intuitive that if you select one of the options that you shouldn't also have to tick the box to the left of the category. It's just one more click I could do withouth.
2. When choosing/applying a color to your photos, I would like to see it done without having to hold the command + a number. This makes it a two handed operation. It would increase the speeed and ease of use if you could simply hit a number to apply colors.
3. Rotation, tagging. It would be great if you could select a number of images to tag and/or roatate all at once. Maybe this is possible but I've tried a number of times to select more than one image to rotate to no avail, same with tagging.
Okay, I'm sure you are tired of my ideas.
