Add a "gutter" to dolphin columns view, to allow initiation of rubberband file selection

[Ian]

I'm curious about a bug I reported to KDE (which they've long since fixed):
https://bugs.kde.org/show_bug.cgi?id=243779

It relates to putting a gutter in each of the columns in dolphin's column view so you can rubberband-select even when there is a full list of files in the column. (Currently, you can only begin a rubberband-select if there is space at the bottom of the column.

This was fixed in SVN literally a year ago:

I'm running Dolphin 1.5 under KDE 4.5.5 on Ubuntu 10.10 (Maverick), and I don't see this feature enabled. When will it hit the Ubuntu tree? Or has it hit already and is still broken?
