Description column is some sort of "other column". Sometimes hard to understand what it show: user description, or metadata summary, or comment from mp3 file, or target.
In Prefs-Advanced we can select what to show there, but no "Description only" option. This is first wish to add.
But primary wish is adding opportunity for visually divide information in Description column with colors/font styles. Example: user description is bold grey, metadata is italic blue. All this may be added to Colors and Fonts settings.
Oops, I've miss this column has been added since 10.0.3.2 beta.
Anyway, maybe in standard "Description" column add option for visually separate user-comment too. With bold or italic for example. For minimizing columns and horizontal scrolling.
