Hey thanks again.
Making a spotify tracker is largely just because it seemed like a good project to test the system, in that it has a bit more complexity than “pull data from EBS and display on overlay/panel”. I am certainly learning stuff in investigating it.
For example, totally didn’t know that I could pop OAuth in a new window, have it do the dance, then have that window close and callback to the window that opened it, all in javascript. Was confused when you said launch a pop-up as to why that would be a good idea, but google helped me out.
With that in mind I think I should be able to have a crack at building this now, thanks for your help!
