+- [ ] Make tree sitter spans truly incremental - or atleast make them pos based and not byte so minor changes only shifts inline
+    - And make inner trees incremental too
+- [ ] Use LSP to add inlay hints in order to test virtual text. then make an iterator over screen that mimics the renderer for scrolling functions.
+- [ ] Add codeium/copilot support for auto-completion (uses the VAI virtual text) as a test phase.
+- [ ] Add a whitespace highlighter (nerd font). for spaces and tabs at start/end of line. not as virtual but instead at render time.
+- [ ] Once renderer is proven to work well (i.e. redo this commit) merge `experimental` branch into `main`. commit `43f443e` on `experimental`.
 - [ ] Add snippets from wherever i get them. (like luasnip or vsnip)
 - [ ] Add this thing where select at end of screen scrolls down. (and vice versa)
