1. This property was indeed reversed in previous versions of the control. Make sure you have the latest version. In the most recent release, the property behaves exactly as stated in the documentation: "Specify Enabled to use 12-hour format, or Disabled to use 24-hour format", i.e. when enabled, the displayed hours range in the interval 1-12, and when disabled, they range in the interval 0-23.

2. TwelveHourFormat is used solely to format the times displayed in the timeline of a Timetable view. The item tooltips are formatted according to the Calendar.ItemTooltipFormat property instead. You can also handle the ItemTooltipDisplaying event in order to further customize the tooltip text.

3. You might want to disable TimetableSettings.ShowPadding to achieve this. The TimetableSettings.EnableSnapping property is used for different purpose - it is used in conjunction with TimetableSettings.SnapInterval to set custom snap interval different than the default one. By default Planner.NET snaps items to cell boundaries.

4. This is indeed the case. This happens because the earlier item is drawn on top of the "busy line" and obscures parts of it. You can resolve this issue by disabling TimetableSettings.ShowPadding.
