I loved Skitch as well and this is a neat app. I wish there was some way of saving a sketch (maybe in LocalStorage) and edit it later (e.g. replacing with new screenshot but keep the markers). I can't remember if Skitch could do it, I use Figma for this today (but it comes with a huge overhead).

What's your use case for persisting the annotations but new screenshots?

Excalidraw.com does exactly this but their arrows just aren't as in-your-face as Skitch's.

Documentation of processes with annotations. There's lots of steps, each step with a screenshot and ~10 annotations and if steps change, I need to recreate from scratch. Doable, but also lots of manual work.

Yes, exalidraw or tldraw are drop-in replacements for Figma that make it save and easy to share, but they are general purpose tools, I prefer single-purpose tools with limited features.
