Atuin seemed like an interesting way to sync shell history across machines. That wasn't a problem I personally had, but I could've seen myself giving it a try.
These recent developments with the Desktop tool, and now what seems like a Jupyter-like replacement for... shell scripts(?)... sounds completely alien to me. I'm sure it solves some problem for somebody, but it's far removed from any problem I've ever had. Good luck with the project, as it does look like a lot of work and thought went into it.
I just hava a zsh binding for using fzf to doing a fuzzy search of my history. The fzf package actually includes the implementation of the zsh "widget".
That's probably essentially the same thing, atuin being sqlite based is possibly faster but its not likely to matter until you reach a very very large history.
