Summary:
User definable taskbar

Details:
Addition to version 1.2.8 (Windows). Make the taskbar (ID, Filename, Path, Volume, Type,...) user definable. User can change order of columns, hide/ delete columns and add columns. Make sorting possible by double clicking the column header tab.

Comments:

Actually, you can define the fields and their order on the grid using the 'Set Grid Fields...' command on the 'View' menu. Allowing one to set the sort order by clicking on the column header would be nice.
