Added a slider to enable the main buttons on the main screen to be scaled. Useful if you're using it in a glider and the phone's mounted an outstretched arm away. Also think I fixed a gremlin with a parameterised call to a procedure with no parameters.
That'll be it for a while I think. I can't think of anything else to add. If you want airfields added or can suggest new features that you think would be useful, please add your suggestions to reviews on the Play Store, or email me.
