I've been struggling with this 'Open in ....' in-app feature for a while, and can't seem to find solution. There's usually a choice between 8 and 10 applications to choose from when you want to open a file in another app - depending which app you want open your file from. Problem here is that often times my most popular apps (iAnnotate, Goodreader, UPad, ...) don't appear in the selections for 'Open in ...' . I've tried deleting some apps that appeared in the menu hoping that it would 'move up' my most popular apps. It worked. But I still need the apps that I deleted. Once I re-installed them, I was back to square one. Any suggestions would be greatly appreciated. Thks.
