I've been using ShareX (https://getsharex.com/) for some years, which is also open-source, and very featureful while not feeling too bloated, though Windows only. I'll have to have a look at this next time I'm on a Linux desktop, as I found the options lacking compared to ShareX last time I looked. - Source: Hacker News / 18 days ago
ShareX (https://getsharex.com/) doesn't have quite this nice UX but it's free. I often use it alongside browser dev tools. Here's a screenshot of me measuring this comment box https://i.imgur.com/yoTHbzq.png. - Source: Hacker News / 4 months ago

ShareX [1] is my other "must install" app. I never would have guessed how much my branch of engineering consists of "take a screenshot and draw lines, arrows and circles on it." Being able to customize my workflow to do all of that is really great. [1] https://getsharex.com/. - Source: Hacker News / 10 months ago

Looks like you want something that integrates well with your workflow. The closest to your description seems to be Manuskript although I haven't used it. But your requirement of "keeping notes and frameworks and linking back and forth" should be possible by stitching together existing Linux tools using a syntax like markdown or asciidoc so that you can use any text editor to write your story and use external tools...
