Version: (using KDE 4.2.2) Installed from: Ubuntu Packages Kopete previously used to allow reordering of the tabs when chats are grouped together. This is useful for logical groupings etc. A similar example is how konsole allows moving the location of a tab relative to the other tabs. A shortcut key should also be provided (eg ctrl-shift left/right, which is what konsole uses)
Dear user, unfortunately Kopete is no longer maintained. Please migrate to another solution, e.g. for Jabber a possibility is Kaidan, for Matrix a candidate is NeoChat.
