Programmed with love by Janie Fury @ Paradise Roller Girls in Hawai‘i.
• Fixes display bug: When a timer is started between jams and the app is set to countdown from 30 seconds, timers will now correctly read "30.0" until the jam starts, rather than reading "0.0", and changing to "30" at the the start of the next jam.
• Minor interface updates
