iOS 9 came with a lot of improvements to your iPad, including two special features: Split View and Slide Over.
Split View allows two apps to run side-by-side, however it requires the iPad Air 2, or the forthcoming iPad Pro. We'll be coming out with updates to take advantage of Split View.
Slide Over reveals a list of other apps you can open and view, and you can take advatage of this feature right now if you have one of the following iPad models: iPad mini 2, iPad mini 3, iPad mini 4, iPad Air, or iPad Air 2. Using Slide Over, you can view a presentation outline while presenting with TrialPad. Here's how it works:
First, be sure you have updated your iPad to iOS 9. (You can check this in Settings-> Genera; -> Software Update.) Next, create your presentation outline in the newly updated Notes app on your iPad. The reason to use Notes is that it now has Bulleted List formatting, and wraps the text nicely so your outline is easy to read.
Then, while presenting in TrialPad, use your finger to swipe from the right edge of your screen (see image below). This will activate the new Slide Over feature, and allow you to select the Notes app, and see your outline.
The outline will display on your iPad, as shown below. The best part is that your audience will not be able to see your outline. The Slide Over feature and your outline will only be seen on your iPad, not on the TrialPad output screen that the Judge or jury sees.
As you present, you may want to make an annotation, a callout, or display a different document. To do so, just tap on the TrialPad side of the screen to dismiss Slide Over, and your outline will like off the screen. Access you outline again by swiping from the right edge again.
