did you change management or so? it is very unlike the good old goodreader standard to charge pro users for a SIMPLE feature that frankly said can also be achieved by iPad’s native settings.
Also: SEARCH has now really become corrupted, showing not only the search term items, but also every single other thing that shares even one letter with the search term. do you know how that looks? ugly black patches all over the page, among which one has to strain the eyes to find the real thing somewhere in there. it certainly looks like a function you yourselves never ever use!
