Hi all. First time poster, don't bite. I didn't see a general software section so posted here, move if required. I'll start off by saying i am not a fan of ipads, i've always been someone who likes fiddling with things, often breaking them, and android just works for me, however i bought an ipad air 2 just to give it a chance and it just didn't work for me. The hardware was truly fantastic, leaps and bounds above and beyond my nexus 10, other than it not having stereo front facing speakers, but the software wasn't my cup of tea (which was annoying, to be honest, it was a pretty sleek device) So while i enjoy tinkering, i have little experience with the more mundane things like office etc. Anyway, I decided to give it to my mother for christmas, she decided she didn't have a use for it, so now my father is looking at how useful it could be. His work involves LARGE legal documents, and he needs to highlight a lot. He asked me whether i knew of any program for ipad that has the ability to highlight text, and then essentially create a post it note for that page, an annotated tab, as you might with a ring binder of documents. Ideally these tabs could be searchable. unfortunately i barely know office aplications on windows, let alone mobile variants, let alone mobile variants on ios. Any help would be greatly appreciated.
