GetExplorerColumnWidth(GadgetID,ColumnID,Width) would also be nice (so it can be stored and while the application starts read the value and set it.
Also to be able to delete a column would be nice (the TYPE column is mostly not needed).
Maybe just set the column width to 0

The ColumnWidth function could be useful for the other ListGadgets too...
(Implemented trough the gadget attribute: '#PB_Explorer_ColumnWidth')
