I gave it serious consideration when the death of Atom was announced and I was unsure where to move on to.
Looks like in the meantime a lot has been done (as far as I remember, TreeSitter and LSP weren’t built in back then…? Not sure though), but the lack of a plugin system is still killing it for me.
TBH it looks like it has 75% of the features you want from a codeditor, which is much more than the use-case for Nano, but no way to go the remaining 25% of the way.
It was pretty great, wasn’t it?
Although I must say. I eventually landed on neovim. Steep, steep learning curve, but now I would not switch back again.
