Managing charts/lyric sheets

New to 1Chart and I'm a big fan so far. Previously I was using OnSong with the chords written in there and it just didn't give me enough options in terms of charting things out.

What are some ways people are managing/organizing their charts and lyrics sheets for rehearsals and gigs? I like using the iPad in rehearsals and gigs incase somebody wants to sit in and play a song I haven't played in a while.

I'm thinking about exporting charts into OnSong as PDFs, one page is the chart and the second has lyrics written out as a giant comment. Or maybe do charts in 1Chart and lyrics as a separate file in OnSong.

I'm open to suggestions, other apps, anything.
