This would be handy for loop systems both the built in loop system and a users own loop system.
Being able to track how many times tasks runs in one instance.
I presume the tally would reset every time you restart runner. Which is fine. The main thing when testing is to be able to click on a task in debugger and see how many times it ran.
If this would seriously slow down debugger, then what about being able to right click a task and a popup appears and we can tag that task to be counted. Or alternatively perhaps instead; when we deselect all the tasks and then this will activate the task counter, and only tasks ticked afterwards will be monitored with a counter for each. When All tasks box is ticked; the task run counter is turned off.
