It would be a lifesaver to be able to set the bookmark zoom level in InDesign (whatever it defaults to now, "Fit Page", I think, isn't great for everyone), so that when it exports to PDF you can already have it set to "Inherit Zoom" (or whatever you need) rather than having to manually figure out a way to do it in Acrobat. When you edit the bookmark zoom level in Acrobat, there's not even a way to do it from the InDesign action that's there--you have to basically create a whole new bookmark, redirect it and then set the zoom level, which is a real pain when you get into really long documents.
