Fix 'manual bookmark' position
I'd love the ability to fix the position of a manually created bookmark in relation to all the TOC bookmarks which are all in the same panel, so that they don't shift around every single time you update the TOC. It is frustrating to have to move them around in a 80+ page document.
Alternatively, would love to be able to easily stop a specific bookmark from appearing in the automated TOC but allowing it to appear in the interactive PDF.
Finally, I'd love the bookmark palette or interface to be bigger, it's a little painstaking to try to drag & drop them to correct places as the scrolling view has a mind of its own sometimes.
