This is not an easy thing to add at all - the component used on each platform is a standard list/table component, so trying to insert an "add" symbol as a big button at the end of the list requires a significant amount of work, especially on Windows where it uses data binding. A much easier approach is to have a completely separate "add" type button somewhere else on the screen not tied to the list that you can tap to just add the next page in the PDF. How about I add that in the undo/redo bar at the bottom left? The fifth icon could be a little plus symbol, and it will be enabled if the next page in the page order is not currently present. I could also add the option I mentioned so I support both cases. Then you can just tap that icon over and over and remove pages when needed. That should work for you, right?

Thanks,
Mike
