Do you have it setup to sync highlights/annotations? how does that work for you?

https://github.com/readest/readest is looking quite promising

I’m not that techy on the screens front but it’s not totally a regular lcd but not as good as e-ink either. It’s kinda something in between. I’ve only gotten to play with it a for a few minutes so far but it’s hard to describe. These pictures do it some justice though: https://www.androidcentral.com/tablets/tcl-nxtpaper-4-fixes-one-of-the-technologys-biggest-hidden-issues

Does the pocketbook app/device let you annotate books? It seems quite interesting but not generally available in the US. Read era does look interesting though.
