-## TODO
-
-Key:
-```
--     : Idea
-- [ ] : Planned
-- [/] : WIP
-- ❌  : Was idea, found usable workaround
-- ✅  : Implemented
-```
-
-- Folds
-  - `[ ]` Org-like <kbd>shift+tab</kbd> behavior: Open folds level-by-level
-  - `[ ]` Optionally not opening all child nodes when opening parent node
-  - Fold siblings and siblings of parent on startup
-
-- Navigation
-  - ❌ Go to parent (as of now you can press `hl` to achieve the same
-    effect)
-  - ❌ Cycle siblings (as of now when reached the last sibling, you can use `hlj`
-    to go back to first sibling)
-
-- `[ ]` simrat39/symbols-outline.nvim#75: Handling of the outline window when attached
-  buffer is closed.
-
-  Maybe it should continue working, so that pressing enter can open a split to
-  the correct location like `NvimTree` does, and pressing `q` can properly
-  close the buffer.
