Has anyone else tried the PR1.2L ctrl-shift-r trick with Witter yet? It works almost perfectly, scaling the icons across the top and bottom bars in a usable fashion. Unfortunately though the message text is truncated on the right hand side; presumably this is a fixed width rather than snapping to the right hand side. I'd show you a picture but the screen rotates back to landscape when I open the keyboard @dwould - thanks for all your effort making a great app. It's getting better with every iteration.
