Small suggestion in Events Sheet.

I think it might be helpful to...in the Event Sheet when clicking on the expressions there is a link to the relevant help for that section.

So there will maybe be a link like in the above pic when you go over each condition, and then depending on where you are will take you to the relevant help file in the manual with maybe an example.

So...in the above example Is Between Angles will go here if clicked on More..

I find another tool does this and it REALLY helps a lot in speeding up finding info to learn.

The help link in the bottom left will do that, once there is documentation.

It's far, far too much work - and probably not even helpful - to make an individual manual entry for each condition, action and expression. Still, it'll at least take you to the manual entry on the conditions/actions/expressions section.
