I have already written a feature request a few weeks ago by email to IDM support for a feature to specify the background color of the lists, some dialogs and the output window to have a different background color as the main edit window.

I liked the prior v11.20 color settings with white background color for the lists, dialogs and output window and grey background color for the main edit window.

If you would like also such a feature write also an email to IDM support.

Edit on 2006-05-21: Since UE v12.00 the text and background colors can be specified for "Workspace Manager / Output Window" in the View - Set Colors dialog.
