In the data grid, when you right-click in a cell and select View Columns, it pops up a list of all the columns. Then you can click on a column to not display it (de-select it). It would be nice to be able to de-select multiple columns. Right now, when you de-select a column, the menu disappears, and you have to do it all over again. It you want to hide 10 columns, this would take a while.
