I'm being picky but if you have a lot of images to make. time saved, maybe.
when you go to save it would be cool if you could just type a file name and enter to save instead of going with the filename provided "testOutput.png"
If I just want to type 1 to be fast, it will not put the .png extension on it and I have to do it manually or stop and edit the file name.
But I can just double click and put a number into testOutput.png like this testO4utput.png then test5Output.png testOu7tput.png.
Otherwise this program is really useful.
It's probably the coolest little app I have come across.
