So I am experiencing a few issues right now which are annoying but doesn't really break the overall experience.
1) First off, its non-negotiable for me as I have a preference to keep my entire library on my device
2) With 2500 epubs, koreader tends to freeze when caching the book covers etc etc. For instance, my first run will freeze when caching epub #567, then I would have to force reboot and continue and this process repeats and freezes and then I have force reboot once more until all my books are cached.

So is it possible to perform this caching process on my PC or something? Failing that is there a way to optimize the cache to reduce the size of the cache?
1. It should be negotiable. Most Readers don't handle 2500 books all that well.

What you could do is put your library on Dropbox and get books from there are you want them.
