Hi,
is there an easy way to get the id of a shape added to the editor via `api('createShape',...)`?
My current workaround is to get all ids from the project source json before and after calling the api and subtracting them from each other.
I'd suggest that `api('createShape',...)` could just return the ids of the shapes created, if I didn't miss anything. At the moment it returns nothing...
Brand new interactions and interfaces. 
Easy to use and quick to get started.
