Does anyone know of an iPad PDF app that allows one to create bookmarks that will show when a file is opened in Adobe Acrobat? Adobe's own Acrobat app for the iPad does not allow for bookmark creation. And while various other PDF apps -- such as PDF Expert -- do, as far as I can tell those bookmarks don't show up when files are opened by recipients using Acrobat. I have a specific need in my workflow for this feature. It's potentially the only obstacle to my using the iPad Pro as my main device and only mobile one. Any pointer would be greatly appreciated -- but I'm beginning think this capability may not exist at present.
