It is the wishlist on dolphiin features and I think it would be great if dolphin can add column view, which makes the exploring much easier, faster and more productive.
Thanks to the effort of the developers and KDE community.
Thanks for your report, and I do agree that this might be a feature worth implementing (even if this is not easy)! There is actually already a report which describes the exact same problem, so I propose to close this report as a duplicate and instead track this wish in bug 387455. Thanks again for communicating your wish & I hope that we can get column view implemented at some point.
