Custom columns determined PER VIEW
"Date Closed" is an irrelevant column in an "Open Requests" view. The ability to customize which columns are displayed should be specific to the VIEW being selected.
It doesn't make sense to have a "Status" column in a "Requests on Hold" view. All those requests have the status of On Hold, that's why they are in that view. Likewise, a "Me or My Groups" view doesn't necessarily need the GROUP and/or ASSIGNED TO Columns. Each view should have the ability to display their own custom columns. Currently, when you customize the columns, it applies to ALL VIEWS.
