@FrustratedReader:
If you care more about highlighting than the quick turn gimmick (I do

), it can be disabled with a hidden setting:
disableQuickTurn=true in the
Reading section.
WiFi being finicky, yeah, but to be fair, it seems to behave a whole lot better than before on 4.12.
The IR grid not waking up is indeed a very old bug on the H2O

. I can concur that it's simply the IR grid not waking up, and not the device freezing, because I had to implement a workaround in KOReader to *always* manually wake the IR grid up on resume.
That said, I haven't encountered it in quite a while in Nickel, on my end. But the potential for it to happen is definitely there
