I use a paper white to read books, pretty much exclusively. Oddly, I find it best to have both the backlight and an external book light, so I guess that says something about my eyesight.

There are two "search"s. The main search will ONLY search titles. It won’t search tags and it won’t search text within a notebook. The secondary search, from within a notebook, will search for text within that notebook. FWIW, you can browse tags in the Tags menu. I don’t use tags (because I can’t search for them), so I’m not sure how useful that is.

I’m grandfathered in to connect, so I don’t pay anything. If I did have to pay, I would not.

Take a look at RCU. That’s the best solution for backups and managing the content of your tablet.

BTW, Connect is NOT a backup.

Good point.
