Comments in actions, 'Wait for previous actions to complete' & more.
If you have multiple asynchronous actions in the same event some expressions like lastdata won't work very well, as there is no set order they will complete in. Is it possible to add tags to those expressions in the future? Or is ajax data (or local storage ect.) overwritten in memory immediately when new data comes in?
Otherwise I'm guessing separated events each with their own wait actions should work as intended?
It's a convenience feature - if you do need to load the results of 3 simultaneous AJAX requests it would be best to keep using the "On complete" triggers.
