It would be useful to be able to save more than 10 screensets.  I find myself using 5 or 6 different screensets for different typical use cases.  I use the remaining screensets for the instruments that will take the most work (1 per instrument.)  For example I'll have a screenset for a rhythm guitar which shows me related tracks, buses, plugin windows and automations. Everything is arranged such that there is minimal pane scrolling/flipping and popup window juggling (yes, 2 monitor setup).  The problem is that remaining instruments that didn't make the cut can be quite tedious to work with (relatively speaking of course).
 
Does anyone else use screensets in this way?

I think it is limited to 10, but I suppose those are per Windows User, so that you could in theory set up a different Windows User to set up some other number of presets.  It would seem a bit unwieldy to do this, but I guess it is there to try out.
 
Or, you could evaluate your screen set use, and just pare it down so that you limit yourself to the most useful ones.

It seems that they are tied to the number keys on the top. The idea being for very quick access. Being only 10 I'm not sure how easy it would be to add more.

I agreed there should be more Screensets available to those who need them. I know I'd use them

For those of us who work on the same project on more than one computer, additional screensets would be helpful. Almost all of the screensets that I use on my main PC, which is multi-screen, are useless on my 2nd (single-screen) setup and even worse on my laptop.
