[Feature request] Grid Thumbnail and number of columns configuration per platform

[juanma-cvega]

Hi,
would it be possible to give the choice to configure the grid thumbnail type and number of columns on a per platform basis? It could be something like a value that overrides the global configuration for specific platforms.
In my case, I would like this specially for arcade games and probably Steam ones as well. I have set up the Box Art type now because I think it looks nice for consoles. But for arcade games I'd prefer the Wide type so I can see a screenshot of the game instead of a box art that doesn't tell me anything in most cases. For Steam games, I'd prefer a grid view the same way it looks on Steam itself rather than the box art but in this case it looks nice as well.
The number of columns would be great because it would allow platforms where box arts are vertical to configure more elements per line so they don't look so big compared to other platforms (take Super Nintendo and Wii U for example).
