So there's a leaked new build today. One thing it does is give some options for switching tablet mode on or off. And I like the tile layout a little tiny bit better than that in 9926. The transparency needs a lot of work though. And I hate the recent / all apps sidebar. 8.1 had this far better. So far, not much other tablet improvement that I've noticed. Edit: The tile layout is apparently tweaked based on your DPI settings. It looks like that at my preferred setting of 125%, but it's different at 150% and 100%.
