Intelligent Automation has 3 events type choices: Time, Line, and Screen Percentage.
If you plan to add an event in a middle of a long text and you need to identify exatly where to insert the event, it's easy for "Time" because the time counter provided, and it's relativly easy with Screen Percentage, but it's a little complicated with "Line" method, because you need to count the actual lines, and sometime it's not simple.
The request is to think about a kind of line counter to make this usuful option more easy to be used.
