I would find it a HUGE improvement to be able to have a existing action, for example Send Email
that has a connection and some info already filled in or not (both would be an improvement) and that you can either have an option "copy/duplicate" this action or that you could copy paste (ctrl + c => ctrl + v) to do so.
Having a switch action for example where in each case a mail should be send, you have to manually create the action each time. There are more cases where this would be a great improvement.
VOTE if you think so as well!
THERE ALREADY IS AN IDEA (that I didn't saw) so vote for it as well by clicking on this link!
This is now completed.
