Aggiornamento 2012 : ora consiglierei davvero di provare vim-powerline che ha sostituito il mio vecchio script statusline, sebbene al momento manchi alcune funzionalità che mi mancano.
Direi che la roba statusline nel mio vimrc era probabilmente molto interessante / utile dal lotto (strappato dagli autori vimrc qui e corrispondente post sul blog qui ).

Tra le altre cose, informa sulla riga di stato delle normali informazioni sul file standard, ma include anche elementi aggiuntivi come avvertenze per: imposta incolla, indentazione mista, spazio bianco finale ecc. Molto utile se sei particolarmente interessato alla formattazione del codice.
Inoltre, come mostrato nello screenshot, la combinazione con
sintetico consente di evidenziare eventuali errori di sintassi (supponendo che la lingua scelta abbia un correttore di sintassi associato in bundle.
