Background Designer Beta Test

Playing around with the beta version of Background Designer, and while I don't like it as well as my beloved PD Howler, I can see that it has potential in the future once it gets out of beta. I had to poke around the keyboard to figure out a few things, but it was fairly intuitive if you have played with other art programs. I never could figure out how to erase some thing without either using Ctrl+Z or deleting a layer, but still fun to play with.
You can find it here if you want to play with it, too.
