I'd like to see mprovements to the software so the Reader displays characters like "ā" or "ū." The "view" feature in calibre displays those characters, but they show up as blank spaces on the Reader and in the Sony software. Like in David Weber's
Oath of Swords, "Tomanāk" comes up as "Toman k." It's not a show-stopper; it's just annoying.
That, and for the Reader to be more stable when an SD card is installed, and not hiccup and lose bookmarks and collections at random. Mind you, I don't
need to carry several hundred e-books around with me -- I'd just like to know that the option is there if ever I feel the urge to. And that the option is stable and bug-free.
