I have some reference material on MOBI and EPUB but its such a pain to try to find a particular spot because the Table of Contents isn't broken down enough. How can I add more detail to the existing TOC or do I need to start a fresh one? On paper things are so easy to find because it usually tells you at the top/bottom of each page the page number and chapter so you always know where you are. As this doesn't exist on digital documents without breaking up the flow (though it could be displayed as an option when needed!), I think I need to redo the TOC.

It has to integrate with the paper version, unlike most ereaders' attempt at showing you the "progress" bar. You can spend several minutes looking for a particular spot on an ereader. This is by far their weakest area that really needs to be addressed.

The problem may be people usually use ereaders for entertainment and not for learning. They get a book (often bought though millions are available for free if they venture away from Amazon, etc), read it and delete it. Its never read again. This is very profitable for the ebook seller! This is very expensive for the consumer!

With good organization (the manufacturers wanting to encourage consumption don't make it easy to organize lots of books at a time on their devices with only one level of folders/collections/groups usually available), you can have quite a pile of books on your ereader. What we need is to be able to organize all our material on our computer, then transfer the entire thing to the ereader. Or link the ereader and do it from the computer. Organizing on the ereader is a tortuous pain.
