Version: (using KDE 4.4.1) Installed from: openSUSE RPMs For me reordering tabs with middle button is not intuitive at all, especially when I haven't really understood what does dragging with left button do (while googling I saw that it drops tab's URL, but why not somehow drag and drop the URL itself then?). If actions of mouse buttons cannot be changed just like that, maybe there could be some settings for that?
Thanks for reporting! *** This bug has been marked as a duplicate of bug 195466 ***
