I only note here the issues and fixes that I looked for immediately because I had reported them earlier for beta 3.
In Dark Mode, selecting an item flashes the viewing pane white for a fraction of a second before displaying it. This was definitely not the case in any of the previous betas and is a major annoyance. I don’t understand how this could have passed testing because it’s so visible and omnipresent, unless different macOS versions vary widely. I’m on 10.14.5.
I’m not sure how much caching makes this better than my previous struggles with large PDFs but performance and responsiveness seem to indeed have improved dramatically.
Highlighting can be undone in PDF so thanks a lot for that, wondering how come it got held up until DT3…
Why were Arabic and Hebrew removed from supported OCR languages?
