Hi there,
I am very new to alfred and I needed a google map workflow.
based on Derick Fay's Rome2Rio workflow, I adapted it for gmap.
That's a very quick one so maybe you could improve it
basically just type :
gmap <starting point> : set your starting point
then it pops up for a destination
And there you go
feel free to do anything you want to improve it
hope this helps
