We've received feedback from clients that they'd like to use the Manage Columns window to reorder fields and rename the field header. At the moment, you need to manually reorder fields on a page by dragging and dropping the fields, which would be made easier by being able to drag and drop multiple fields from the Manage Columns area. Renaming a field Header is also a one-by-one process, by right-clicking on a field and going to Format > Rename Header.
Please add your support by clicking on 'Me too' if you'd like to see this extra functionality as part of Manage Columns.
