Same. Thousands text editors, but not a single IDE.

And they all get SO close, just give a look to SetEdit screenshots: https://setedit.sourceforge.net/

I don't know if it can be of any help for you, but at the moment on the terminal I mostly use:

- Tilde: https://github.com/gphalkes/tilde

- Textadept: https://github.com/orbitalquark/textadept

Or "Geany IDE" on desktop environment (while waiting for lapce.dev to get better), I tend to stay away as much as possible from VS Codium, but everyone else seems to love it and already forgot about Atom, few seems to realise how Microsoft really is.

Maybe the plot twist is that you have to accept in your heart that "writing text on anything, is the real IDE", and transcend to writing on nano!
