An interesting one I found was CudaText (https://cudatext.github.io/), which has a lot of features and is a solid editor but... it's written in Free Pascal. That's not a technology I want to deal with for what would be my #1 tool.
I'll definitely be trying this out for myself soon, but it'd be helpful if you could include some side-by-side screenshots comparing the font rendering of your fork to the original, considering that's one of the main differences.
