Description
Is your feature request related to a problem? Please describe. I have a MBP 13", I also have a 49" ultra wide. On my ultra wide, I use 3 column middle layout, on my MBP display I use fullscreen. When I open the app, one of the displays will have the wrong layout since I can only save one implicit default layout (the first in the list).
This is exacerbated by the constant crashes, which means I have to restart Amethyst multiple times per day.
Describe the solution you'd like I would like to be able to save a different layout for each display, so that when I start Amethyst, the correct layout is selected for each display.
