A Softpedia review of QIP 2006 mentioned its unique feature (at the time) of tabbed message windows—instead of a message window for each chat session, one window with several tabs is shown. Since this feature's introduction, ICQ Version 6.0 now includes this feature, as do the multi-service clients Pidgin, Miranda NG, and Trillian. Other features include integrated mail.ru e-mail client, and a wider range of emoticons. QIP presents no advertisements in the application windows; this is described as a security advantage.[11]
New version of QIP named QIP 2010 contained all features of Infium and interface of QIP 2005.
