Lines are coloured based on a semi transparent version of the Priority colour.

The list of calls will load with the newest call at the top based on Date Created, when selecting one it will present it in detail in the details tab.

The Column filter will filter on the data in the current dataset. Where the main filter will re-fetch the dataset based on the new criteria.
