I add some steps inside each event and check it on screen by doing something like this:
Condition 1: Set text Debug to "Debug start";
Condition 2: Check something;
Action: Append text "newline & Step 2 Success" AND do the action for this Step;
Sub-Condition 2.1: Check something;
Action: Append text "newline & Step 2.1 Success" AND do the action for this Step;
Sub-Condition 2.2: Else Check something;
Action: Append text "newline & Step 2.2 Success" AND do the action for this Step;
And so on...
