The control use to filter resources (e.g. aircraft, instructors, boats, etc.) on the schedule page is being changed to allow more flexibility in which resources are being selected for viewing. The original resource select control (pictured below) only allowed for a single resource or a single resource group (e.g. All C172N) to be selected. This did not work well for users that might want to view similar aircraft with different model names (e.g. multiple types of C172s, or maybe all C172s and Warriors).
The new resource select control allow selection of multiple items in the list. The picture below show selection of 'All C172N' and 'All C172SP'. To select multiple items in the list, you must hold the <Ctrl> key while making your selections. Then click 'Refresh Schedules' as usual to refresh the list of schedules. If you would like to save your new view as your default, do not forget to click on 'Set this as your default display', which is located just above the multi-select control.
