I am in the middle of learning it myself. The GUI is good and easy to learn. But there are a lot of tricky things you need to do to get a post. You need to make all the changes in the UPG to the .SRC file and then compile it...sounds easy right? Not so much.
- The UPG will only work on posts that were created in the UPG. There is no way of telling this until you try to load it.
- When you load the supporting files for the CTL file, you can load them in the wrong order.
- The UPG has crashed on me several times and the only way I found to repair it is to uninstall it and reinstall it.
Besides that, its awesome!
