I agree that reviewing hightlights on a kindle is excruciatingly painful when there are more than few highlights.
I use KRDS from the thread
https://www.mobileread.com/forums/sh...d.php?t=322172 to get a list of highlight locations and azw3r.pl from the thread
https://www.mobileread.com/forums/sh...d.php?t=321811 to extract the text of the highlights from the book.
I also use notes_insert.pl from the second thread to make an HTML file of the text of the book with the highlighted text as bold.
The output of azw3r.pl can probably be put into evernote, but I know nothing about that.
azw3r.pl is for books in KF8/azw3 format. KRDS can generate a list of highlight locations for KFX books, but I do not know of anything that extracts the highlighted text from KFX.
