The problem with the tutorials is there is a lot to learn. It really is best to dive in and try to accomplish something small; asking questions of the people here when needed.
The hardest things to figure out are the following:
- What events can be triggered? (event='show_window')
- What notifications can send triggers? (notifiyOnRightClick='true')
- What things you can't do... there are WAY more of these than things you CAN do.
- What settings are available for each window/element.
Have fun with the puzzle and ask for help when needed!
