Dash - Clicking on the main left hand side preview image in a Dash Preview should close the Preview and return the user to the results view

Bug Description

Clicking on the main left hand side preview image in a Dash Preview should close the Preview and return the user to the results view.

In user testing almost all participants tried to click on this image when they were asked to close the preview.

What about bug 1037959 and the solutions suggested there ?

@mc-return; we are looking at that as well, these two requests are not mutually exclusive

@johnlea; Great, because usually a context-menu opens on right click, another right click closes the context menu, while you choose items in the context menu with the left button.

As the previews now are Unity's version of a context menu (consuming the right click and presenting context about items), IMHO it would feel most natural for users if controls would be equal to one.

Also learning this behavior would happen very fast for any user: you right click once->preview opens->right click again->preview closes->learned.

Another additional button presenting the context "Exit Preview" or "Close Preview" or "Back To Dash" or "Back To Results" would be ideal to solve all exit problems for every user, even those who do not use the right button normally at all and just clicked it accidentially...

@mc-return; good idea! ;-)

I've reported your idea as a separate bug, see bug #1046315
