I prefer Okular reader, but all I ever do is read. Notes and highlights really belong in the source document… eg in .tex file or in Word or Office.
Editing pdf files is a modern idea.
I have some ebooks about Java in pdf format and I need see, create, update the “notes”.
Same way I need highlight any paragraph as need it. Therefore the only and unique source available for me is the PDF file, there is no neither a .docx or .adoc file
Anyway I will see your suggestion, perhaps exists some extra plugin to install
I’ve now moved to using GNOME Papers which you should be able to download from Flathub via your disro’s software application.
Create/update notes shortcut = s
Select a paragraph and highlight select text then Ctrl+H
Can’t speak to your question about Windows (haven’t used it for over 10 years) but as the app is a Flatpak, perhaps that will be possible?
I rarely edit PDFs I didn’t create from my own source. In case I need to touch foreign PDFs, I use an Online service like Stirling PDF.
Thus, I don’t have to install anything.
I know that this might end up in a privacy concern, but I can live with it.
