Use the Customise views command to create your own view definitions, containing just those columns or properties you are interested in:
You can adjust column widths in a list view by dragging on the column divider line in the header row. If you make changes like this then bring up the Customise views dialog you are asked whether to import the current column widths into the view definition. You can then save the view definition including the column widths. (If you do not save the column widths in this way then they will only apply as long as the current window is open.)
You can also rearrange the order of columns graphically by dragging the column header. However, you need to use the Customise views command to add or remove columns.
Three user defined fields User 1 to User 3 are available for additional keywords or notes. These appear at the top of the clip details dialog, and you can define your own custom labels for these columns, and whether they should be used for grouping or not.
The Professional Edition has an unlimited number of user-defined fields. The first six of these are shown at the top of the clip details dialog, though you can access any of these fields via the details table or in a list view.
When you import clips with QuickTime Meta data, such as ID3 tags in an MP3 file, or Exif tags in a TIFF image, you can set it up so that the value of these tags are automatically copied to specified user defined fields. Simply give a user defined field the same name as a meta data tag (eg. "Flash" or "FNumber", "Artist" or "Track") and that column will be filled in automatically at the time of import.
