There's a wildly out of data repo here[1] that I badly need to push updates to, and with the caveat odds are there are lots of missing pieces that'll make you struggle to get it working on your system. I wouldn't recommend it - I dumped in Github mostly mostly because why not rather than for people to actually use.
Difficulties will include e.g. helper scripts executed to do things like stripping buffers, a dependency on rofi when you try to open files, and a number of other things that works great on my machine and not so well elsewhere.
I have about 2-3 years worth of updates and cleanups I should get around to pushing to Github that does include some attempts to make it slightly easier for other people to run.
The two things I think are nice and worth picking up on is the use of DrB to get client-server, which means the editor is "multi window" simply by virtue of spawning new separate instance of itself. It's then multi-pane/frame by relying on me running a tiling wm, so splitting the buffer horizontally and vertically is "just" a matter of a tiny helper script ensuring the window opens below/to the right of the current window respectively.
But some other things, like the syntax highlighting (using Rouge) is in need of a number of bugfixes and cleanups; I keep meaning to modify the server to keep metadata about the lines and pull the syntax highlighting out so it runs in a separate process, talking directly to the server, for example.
