Suppose a business has a custom field in all tickets that corresponds to a field in Zoho CRM for a contact's geographic location in the United States (West, Mid-West, East). An administrator could configure a custom view for the business that would sort tickets according to these three categorizations and differentiate the tickets according to which section of the country the contact's custom field lists with labels that are yellow corresponding to the West, Blue to the Mid-West, and green to the East. These can be sorted alphabetically or manually sorted by simply dragging boxes for the corresponding labels around in a new screen in the Sort menu in a manner that is similar to how users can rearrange custom fields in the Settings now.
If they wanted to, they could also set it up so that tickets were split into three sections with headings along with the color-coding. These could then be "sorted" by simply using a hotkey (or menu button) that activates a "Move" mode and dragging the sections around.
