 # TODO
 
+- [ ] Overwrite empty space between line number and line. (in the renderer)
+- [ ] Make iterator for next/prev line reuse same allocation buffer (so only free once with iterator).
+- [ ] Add tab/untab with [,<] and [.>]
+- [ ] Add something that works like `p` but doesnt move cursor.
+- [ ] Fix the fact that hooks arent updated when a line is deleted/added.
+- [ ] also use this sorta rules apart from previous lines indentation for the indentor.
+    - if previous line ends with { or similar → indent +1 
+        - (i.e. just check the last line that is not string or comment or empty)
+    - language-specific rules later if you want
+    - ignore comments that dedent etc. - anything else should be handled by LSP.
+- [ ] Fix bug where clicking outside eof sets to top.
+- [ ] Add this thing where select at end of screen scrolls down. (and vice versa)
+- [ ] Add a virtual text support (text that is rendered in the editor but not in the actual text)
+    - Add a whitespace highlighter (nerd font). for spaces and tabs at start/end of line.
+- [ ] Add support for LSP & autocomplete / snippets.
+    - First research
+        - `textDocument/documentHighlight` - for highlighting stuff (probably tree-sitter is enough)
+        - `textDocument/selectionRange` //
+        - `textDocument/completion` - Obviously
+        - `textDocument/onTypeFormatting` - seems promising for auto formatting (indentation etc)
+        - `textDocument/inlayHint` & `textDocument/inlineHint` & `textDocument/codeLens`
+        - `textDocument/formatting` & `textDocument/rangeFormatting`
+        - `textDocument/semanticTokens/*` (probably tree-sitter is enough)
+        - `textDocument/linkedEditingRange` - probably useful
+        - `textDocument/foldingRange` - i will never use this for folding but it might be useful for other things.
+        - `textDocument/rename` & `textDocument/prepareRename` - probably useful
+        - And a lot more (just go through each for `clangd` and then expand to say `solargraph`).
+    - Make a universal plug for lsp. So focus more on making a general purpose solid communication interface. Instead of something specific.
+        - With a 4ish pass system. (more like each returned value from the lsp is used in 4 ways)
+            1. One for stuff like jump to x position. or rename symbol x to y. (stuff that explicitly requires user request to do something)
+                - Maybe even hover goes here
+            2. One for stuff that only affects highlighting and styles . like symbol highlighting etc.
+            3. One for Warnings/errors and inlay hints etc. (stuff that adds virtual text to the editor)
+            4. One for fromatting and stuff like that. (stuff that edits the buffer text)
+- [ ] Add snippets from wherever i get them. (like luasnip or vsnip)
 - [ ] Add support for virtual cursor where edits apply at all the places.
 - [ ] Add alt + click to set multiple cursors.
 - [ ] Add search / replace along with search / virtual cursors are searched pos.
 - [ ] Add support for undo/redo.
 - [ ] Add `.scm` files for all the supported languages. (2/14) Done.
 - [ ] Add splash screen / minigame jumping.
-- [ ] Add support for LSP & autocomplete / snippets.
 - [ ] Add codeium/copilot support.
 - [ ] Normalize / validate unicode on file open.
 - [ ] Add git stuff.
+- [ ] Add SQL support. (viewer and basic editor)
+- [ ] Add color picker/palette for hex or other css colors.
 - [ ] Fix bug where alt+up at eof adds extra line.
-- [ ] Think about how i would keep fold states sensical if i added code prettying.
-
-- [ ] Retry get proper blocks from tree-sitter.
-    - And use it for full block selection (including inline ones).
-    - And for indenting.
-    - And highlighting block edges etc.
-- [ ] Add feature where doing enter uses tree-sitter to add newline with indentation.
-    - it should also put stuff like `}` on the next line.
-- [ ] Add the highlight of block edges when cursor is on a bracket (or in).
+- [ ] Think about how i would keep fold states sensical if i added code prettying/formatting.
+- [ ] Use tree-sitter to get the node path of the current node under cursor and add an indicator bar. 
+    - (possibly with a picker to jump to any node)
+- [ ] Add the highlight of block edges when cursor is on a bracket (or in). (prolly from lsp)
 - [ ] Add this thing where selection double click on a bracket selects whole block.
     - (only on the first time) and sets mode to `WORD`.
-- [ ] Redo folding system and its relation to move_line_* functions.
-- [ ] Also try regex based indentation.
-- [ ] And indentation based blocks
+- [ ] Redo folding system and its relation to move_line_* functions. (Currently its a mess)
