There’s Zotero. I haven’t used it but seems to have a feature called ‘Collect with a click’ which should allow adding bookmarks.

No prob! 😊 👍️

Thank you, I’m pretty proud of myself as well. I was already prepared to re-install from scratch, because I have backups in place. I still can’t understand why a tiny programme completely borked Software Center, but apparently Windows and Linux don’t mix at all, unless you use Wine.

My upvote goes to Master PDF Editor as well. Only PDF reader/editor that can do annotations and notes sufficiently well, in my very personal opinion.

Tauon Music Box available on Flathub. You look for albums by typing on your keyboard. Once you see the result which says “Artist”, hit enter. It creates a playlist which shows all the albums of that playlist. The next time you want to listen to that artist, start typing and select “[Artist name] playlist”. This concept differs from a traditional concept of playlists, because it doesn’t actually create playlists you can use or export. I just like the UI, although the play controls are bit weird, they don’t quite work the way you’d expect them to. It’s a new project but worth keeping an eye on.

FocusWriter for a minimalist, focused writing experience. You can edit the existing template for a dark theme and white text. I rather like the typewriter font, Liberation Mono (it was Courier something back on Windows). Give it a try. I’ve been using it for around 3-4 years.
