In the German manual written earlier this year, there is a ColWidths key (I forget in which INI file!) which allows the Playlist column widths to be altered.
1: Is this option still available?
2: Could Torben please explain what all of the Playlist columns are, from left to right (I know the first one is the player/backtime column, but some of the other ones at the right are not obvious)?
3: Does this option work differently (or at all?) if Extended View is selected in a Playlist?
It is still available, in layout.ini. The columns are those you see, from left to right: Time,Title/Artist,Duration,Ramp,Length,Arrow
The artist column in non-extended mode is a virtual one (title and artist are drawn manually into one column), so it’s the same settings in both modes.
