cache thumbnails that have been generated at least within a file open session

I understand that saving thumbnail images of pages in files was eliminated to reduce file size. However the current state of viewing pdf documents in thumbnail view could be drastically improved by not having to redraw thumbnails every time the scroll bar is moved so that a thumbnail goes offscreen and a new thumbnail pops up.  Also, having to redraw every thumbnail if a single page is rotated makes no sense.

Obviously this is not an issue if you only have 5 or six thumbnails, but if you've dragged the thumbnail pane wide enough to get an overview of an 80 page document, this can be really, really annoying, especially if you're editing the document by moving pages around.

Could someone with some clout please fix this very easy problem?

Thank you very much!

Using the Acrobat SDK maybe you could embed thumbnails (with a plug-in). Are you a plug-in programmer?

This sounds like you have a compliant about a specific version of Acrobat or Reader, not about our SDK. What version of which product on which OS platform are you seeing this behavior on??
