I wonder if there’s room for integration with Vim/Neovim or the plugins in that ecosystem - I feel like there’s a strong overlap between the “vim language” of text objects, motions, etc and the structure editing this project is working with.
We have plans for adding a keyboard interface [0] at least, though it's still an open discussion. If you're after straight Neovim support though, perhaps nvim-treesitter-textobjects [1] might tickle your fancy?
