Dedicate each dashboard item list to its own column

[JosephFerano]

Hi, thanks again for the great package!

I wanted to know if there was a way to dedicate each dashboard item so that it's in its own column side-by-side with the other item columns. Here is an image of the general layout idea;

As you can see, the columns are side-by-side in this layout. Would be nice if recent files, projects, bookmarks, etc; each had their own separate column. Slightly related to #302.

Sorry, but there isn't a way to do this yet.

I think this might be a good time to add more layout to this package? Feel free to give this a try and make PR, etc.
