Or you coukd just use Arch without installing an AUR helper?

In vim you can make some changes to a file, close vim, and then reopen the files, and then undo your changes, i.e. your undo history persists across sessions.

I use helix part-time but am forced to go back to neovim a majority of the time for a few reasons:

1. no persistent undo
2. no ctags and cscope (some C/C++ projects don’t work well with clangd)
3. niche plugins (e.g. I just found a neovim plugin that gives me a way to run ipynb files in-editor)

If 1 and 2 got fixed, I’d be a full time helix user

Biggest con of KDE + Krohnkite (to me) is no text-based config. I really have no desire to pour through the GUI to set up all my keybinds. I’ve tried this setup before, and honestly I mostly like it. However anytime I want to change something I just hate having to click through a menu with my mouse. The search bar helps, but often you’ll spend a lot of time guessing what the devs decided to name a setting. I went back to Sway and have no regrets. Though I’ll admit I wish there was something that was basically Sway with the benefits you mentioned here.
