I also think they should let us see all the stamps too, because I have over 200 deleted stamps that are taking up room in my stamps folder, and I don't know which one to delete. They could get rid of stamps.def, let you name stamps instead of using the time as a number for the file, and also make it so that when you press the delete button, your stamps are actually deleted, and not just removed from the browser.
By the way there is a bug in the stamp browser, some stamps are repeated twice on different pages. The problem is this line: # define STAMP_X 4
