I realize as said in the official thread 0.9.5.2 allows "autosizing" of columns, but what I'm after is a little different. Instead of having to stretch columns to the extents of the playlist view, then have them auto-scaled, i would like them to fill the window automatically. The manipulated columns within that would auto-scale. The reason being I don't like void space in the Playlist view, and it's a pain to stretch the last column 100% to the edge of the playlist view without generating a horizontal scrollbar.
My thought of how this could work for the end user is similar to sizing toolbar buttons. Would it be possible to fill space by double clicking on column separators (i.e., button grips) to have them slide over filling the void space?
