I'm more than happy to compensate app devs for their time and even just a nice GUI/UX on something that's already baked into the system if it makes a job easier, but this app is full of bugs (crashing constantly and leaving artifacts of the color palette on my screen)... Besides those issues, you cannot really test the app well because even the included stuff pops up with a payment screen to buy access to the basics. At the very least, put the cheapest option as included with the small price tag and then add options to expand the abilities. Nope, no thanks.

Simple to use and images are easy to lose. If an update occures, or simply closing down and reopenting your mac, all your hard work in adding images disappears.

Its as simple as this; it doesn't work. I will get my $3.99 refund, but don't make the same mistake that I did.
