Version: 2.2.1 (using KDE 3.5.6, Kubuntu (feisty) 4:3.5.6-0ubuntu14.1) Compiler: Target: i486-linux-gnu OS: Linux (i686) release 2.6.20-16-generic KTorrent defaults to having two tabs, one "Uploads" and one "Downloads". There are also "New Tab" and "Close Tab" buttons. However, the New Tab button only adds tabs of type "All Torrents", and once a user has deleted the Uploads and Downloads tabs, there is no way from within KTorrent to get them back. I am using KTorrent 2.2.1 on Kubuntu feisty-backports.
Click on the groups button on the side, there you have a bunch of groups in a tree. If you click on one, it will be shown in the current tab. You can also directly open a new tab with a group by right clicking on it and selecting open tab.
