- Revert to more "stable" iPad idiom
- Set accent color the proper way
- Use .tint when available
- Unify navigation style by idiom
- Retain navigation bars in sidebar/detail
- Lighten sidebar appearance
- Fix Menu style (dropdown -> button)
- Use native Picker (dropdown)
- Use switch toggles rather than checkboxes
- Replace .actionSheet with .alert
- Increase minimum row height
CAVEAT: on Mac with iPad idiom, having a Section in .sidebar
produces artifacts. Header keeps changing height for no reason.
Retain Section on iPad multitasking only to not break navigation.
