Greetings: We try to use the iPad app at every service, but there are a couple of things that cause us to revert to the "at computer" control. It seems certain powerpoints (especially those with dark backgrounds and light lettering), so up as black boxes on the iPad. They look fine on the computer, but since you can't read what's on the slides it's very difficult to navigate. I can supply slide example if you'd like. Also, a feature that would be nice, is the ability to drag the size of the slide list window up/down in order to manage the navigation better (more slides = less visual acuity, less slides = better visual acuity). I must say that using the iPad on a Retina iPad is very nice and even the small slide text is very readable, but the ability to make that window larger, would be helpful for these old eyes.
While I'm discussing features, there seems to be a continuous problem with slide numbering in the slide preview window on all platforms. If I have more than 9 slides for a song, the program only numbers slides 1 thru 9. This is problematic if I need to remember which slide a chorus is on (unfortunately, my worship team does not put the slide in order). I've mentioned this before, but so far there doesn't seem to be a resolution.
Thanks - John
