How about making the toolbar adjustable in size? It would be nice to be able to read the icons and touch the one I want. I'm old and can't see well in the dark. I would like it to be easy to see and touch the + or - icon without accidentally locking/unlocking the screen. This size should be for the toolbar only and not tied to the general font size.
I use an ipad mini mounted on my 17.5" dob. When it works (will look in another blog for answers to that) it is fantastic. I'm disappointed that there doesn't seem to be many features or improvements aimed at visual observers.
