Many times I do the following:
- Copy state name by right-click in State Machine Explorer window.
- Go to state where it should be used.
- Right-click on the wire -> select "Add State(s) to Queue" function.
- Right-click on the "Add State(s) to Queue" function's input -> create constant.
- Then double-click on the constant, and paste state name from the clipboard.
Maybe it could be possible to simplify steps 4 and 5 by adding copied state name to right-click menu, so it could create input to "Add State(s) to Queue" function as string constant with state name.
Also, with the similar approach steps 3-5 could be simplified, when "Add State(s) to Queue" function will be placed already with string constant with state name connected.
And the last one (but a bit odd idea) - that one could right-click on state from State Machine Explorer, and select something like "Add Transition to State". So then steps 2-5 could be simplified.
