I'm currently running on a fork of Helix text editor, which I heavily gutted to replace the block cursor with a beam-style (like one in insert mode, but just all the time). Since the maintainers are drowning in PRs (472 open ATM), I understandably don't expect them to have time for my weird ideas. Then I pile on top whatever PRs I want that I find useful out of these 472, and with a little bit of LLM help I have a very different text editor than the upstream.
