Huh. Can't upload a screenshot. That's weird.
Mobile technology is freakin awesome these days. OMG.
I use mobile sheets pro for my sheet music and PDFs on a tablet live. Mainly because it allows you to hand scribble notes, syncs to a cloud, receives MIDI commands (that way if I chance patches on MainStage, it changes the song), and it reads pro-chord format. This allows you to transpose the key, then it transposes the entire song on site. Also allows you to pre-order setlists.
I use Planning Center for a rehearsal/organizational platform. It databases everyones phone numbers, emails, and google accounts so you can schedule rehearsals, have inline chat functions, and can link iTunes, youtube, soundcloud, and Amazon media sources to each song in the bands repertoire. When you set up and schedule a rehearsal, everyones iPads and tablets sync to the rehearsal agenda, so the pdfs of all the sheet music is automatically synced to each band members iPads as soon as they get to the practice or gig. It also syncs to the sound, lighting, and video guys iPads or smart devices, so that when you're in full dress rehearsal, they can follow the tech sheet (thats the list of order of events in the show).
It has a really neat transpose function, so if the song "Don't Stop Believing" (which is in E) is transposed to Eb (because no one can sing it in the original key), then any musician in your band who's rehearsing the track, can transpose the file down, and practice along with it instead. This is all from ON the mobile app, so no need to download the song.
It even keeps track of what songs you played when, and how many times per year you played them, then spits out your setlist to the CCLI and Harry Fox unions so if you can pay the correct performance royalties. Really cool. Takes off a lot of leg work. Also helps manage some of the accounting and booking stuff. All from a cell phone. Crazy huh!
