Excellent question. I experimented with this a bit this morning to see what I could come up with for you. I believe you could add a small sidebar to the right hand side. What would work best is one that has space for about one widget. You could fix it in place either at the top of the screen on the right, the middle on the right or the bottom on the right. Beyond that, it just doesn’t work well with the layout as it is. The widgets end up in odd locations.
If that’s in line with what you have in mind, let me know and we’ll go from there.
