Clementine music player implements the mechanic by right-clicking a column header. foobar2000 and Directory Opus use an internal menu.
Even if the options were just added into the Advanced section, or even if I have to modify a .ini file manually... I would love this functionality. The layout in which I prefer my columns looks extremely ugly - some pairs of columns are scrunched together and some pairs of columns have huge blank gaps between them.
Please and thank you!
