This is just a suggestion: it would be nice to have a "tag" property on the colModel (or something like it). This would be a property that could contain any value and would allow the developer to classify columns in the colModel.
For example, you may want a standard view and extended view(s). You could tag your View columns for each and hide the extended view by default and also hide them from the drop down column select (in the case of show/hide) demo. Developer could setup postData to render request full or partial view and colModel could adapt appropriately.
I know there are ways around this, but it just idea for future enhancement.
Thanks
