Bookshelf view! The covers are sooo beautiful on the e-ink screen, please let me see them!
“Good” PDF support. Kindle v2 was “awful” PDF support. Here at v3.1 we’re all the way up to “poor” PDF support -- that’s progress!
Not displaying the empty margin space would be a good start to make things more readable.
The ability to password-protect all access to the Kindle store (so I can hand my Kindle to friends for an evening and not worry about them inadvertently purchasing half my samples!)
I don’t care which formats we use, but I do want Epub’s ability to display images inline instead of just on the next line. So I guess I do care about formats after all...
After editing a comment it’d be great if the Kindle could re-flow the text display around it, so that I could see my comments inline instead of hiding them behind an anonymous clickable number.
I’d like something akin to bookmarks but that are linked to the 5-way controller, so with a click I can jump between locations that I set. The way certain books have section breaks that you can step through with the 5-way; I want a customizable version of that.
A menu item to reset my farthest-read point in a given book. Either to the beginning, or to where I am now. Please!
An auto page-turning function so I can use the Kindle hands-free, like while exercising. Maybe while in that mode display a bar in the margin that jumps from top to middle to bottom, so we have an estimate of when the page is going to turn on us (limited to how much you want to refresh the e-ink screen of course).
An advanced preference to only do the full screen refresh/flash every few page turns, the way the Chinese Kindle OS “Duokan” does it. The e-ink screen gets a bit dirty after 3 turns or so, but I’d be willing to trade that for the black flash.
And of course more font/formatting options.
