When I work on modeling microflows, I tend to end up copying and pasting a sub-microflow call into other microflows quite a lot.
For instance, I’ve created a specific microflow just for logging purposes. Since the call to that microflow is usually more or less identical each time, copying and pasting feels like the easiest option.
If there were some kind of “favorites” section on the screen where I could save this specific clipboard item, it could, in a way, make development much faster. It would be similar to how the toolbox is currently set up in Studio Pro.
Of course this could be done with other elements too, like snippet calls, show page calls, java action calls. Evertyhing that is copy/paste-able.
