Description Yousef H 2016-01-06 06:42:16 UTC 
The URL describes the issue quite nicely. Please ignore this if possible.

 The current three layouts, are basically the same with one difference(AFAIK); one row, dynamic rows, or custom rows. I am not talking about those. layouts. The issue appears when one use multi monitors, where each monitor is showing its view of each VD(virtual desktop). What I want to suggest is, to have the whole VD show up in one monitor.

Reproducible: Always

Tbh, this is unlikely gonna be supported since it very quickly reaches its limits, notably when there're more than two screens or generally the combined aspect ratio runs "out of bounds".

Also you're wasting quite some screen estate, notably when presenting windows in desktop grid.

On top of that this approach exposes windows on other screens (we frequently get bug reports when this happens because the audience is confronted with windows they're not supposed to see)

As the additional concept would add quite some (more) code complexity (lots of branches and code doubling) to a class that already is overly complex, there's probably much reluctance to add it as option, notably if the only pro of the concept is "I'm used to it from unity" - sorry.

Sorry, this cannot work for screens with different aspect ratio. It's the same problem as cloning in general. Just doesn't work any more with the current available hardware.
