Sure. Bear in mind I'm not a super-nerd, so some things were more difficult for me than they should have been!
It was a little tricky to get my head around setting up what I've called "trigger sequences" - incoming triggers that then trigger other "action or logic sequences". It might be good to have a simple explanation of these, with maybe some worded examples, flow diagrams etc.
It also took me ages to work out how to properly create and read nested IFs. I kept pressing the pencil instead of the + on the Else statement, so creating a consecutive action instead of the ELSE action. That whole area was a bit tricky for me, but probably wont be for others. It might help to colour code the levels of nested IFs, or make the indents more pronounced, and to have tool-tips when you hover over the various edit icons?
Once I'd worked it all out, everything was super-easy and fast, and incredibly powerful. The nested IF/ELSE statements in particular are brilliant. Seems a lot less temperamental than Apilio, more stable. I have to run various extra actions in Apilio to recheck states periodically and make sure the correct result states were being achieved. I need none of this here..
