Hi! There is a request coming from users of Krusader who want to share their user actions (similar to Dolphin service menus). A new category "Application addons"->"Krusader User Actions" would be great.
AFAIK there was already one on kde-files.org, link might be
http://www.kde-files.org/index.php?xcontentmode=660x661x662x663.
Thanks!
