I have a slow network, unfortunately.
The biggest improvement I see is that it never takes more than a few seconds to start reading, and I no longer have to reload to see the publication. I also like that it displays a message for events that are missing from the relays, as I sometimes got confused, otherwise.
About halfway down the book, I start having to click the button at the bottom, to see the next chapter, which is tedious. And the _Penteteuch_ is in some sort of doom loop. 😂 Woops.
Here are some good choices, for testing the new loader.
_Joan of Arc_ by Mark Twain is complete.
_Genesis_ in the KJV is incomplete. So, you can see how the info message looks, on that one.
