We love animated thumbnails within Shotgun. We love them so much, we migrated our FX library to Shotgun.
BUT. We want to be able to Play in RV any time we see an animated thumbnail, regardless of the context.
For example, you are looking at a Shots page, you see an animated thumbnail, right there is where you want to right+click and Play in RV.
Or more fundamentally, you are on the Versions detail page ( a place which is all about Versions ) and you want to Play in RV.
Basically if it moves, Play in RV!
