Can you add a new window called "Interactions" to save interactions?
When an interaction is used in many events, it should be useful to save it, and then to be able to call the saved interaction on the event window.
You can also add an "Action" window to reuse action :-)
Practical example :
If we want to modify an interaction, we have to modify it on one event, and do a copy-paste on each event concerned. It's a great source of errors and a waste of time.
The good practice should be :
An interaction have to be prepared in the interaction window, and then used by the good events when necessary. If we modify the saved interaction, no problem!
