The new ability for users to freeze columns in data grids is very helpful. As a UX designer, it would be very helpful to save the current freeze column settings of a table portlet as the default user settings for the portlet, in the same way we are currently able to save column order and column widths by clicking the "copy from portlet" button in the Data Source Columns section of the portal editor. This would save us the trouble of having to teach every user how to use the freeze column feature and have them set that setting on every page for every table portlet where it makes sense to have the first columns frozen. Also if they unfreeze columns, being able to click the "clear user settings" button to easily return the portlet to the default frozen pane settings would be very beneficial.
