It would be nice to have the ability to check if a particular column in a Grid has been hidden by a user. We display a lot of data in grids and our users hide columns they don;t wish to see. We want to give them the ability to save their choices (about what column should be hidden). Right now, we have a separate screen where we show them a list of possible columns and they can opt to hide/show them. A much better way would be for us to simply allow them to hide/show using ZK's AUTO menu popup and then opt to "save the current layout".

If we had a way to check Column.isHidden() or something like that, we could easily detect their choices. Alternatively, as a second-best option, if the column or grid supported an event that was triggered each time a column was hidden/shown, we could try keeping track of this ourselves.
