Mission control el capitan desktop thumbnail I have recently moved from Snow Leopard to El Capitan, and there is something I'm missing currently and hope it is a gesture I don't know. 

In Snow Leopard, when looking at all your desktop (Exposés and Spaces) it was possible to get what is actually Mission control, but on all the thumbnails of the other desktops.

In a quick view, it was then possible to expand all the windows of all the desktops. I don't know how to get that with El Capitan.

Thanks
You are looking for mission control by gestures ?

Settings -> Trackpad ->
