-- Important: Put this in your config directory at lua/nvim-tree/renderer/decorator/bookmarks.lua

-- HACK: Although this file is named bookmarks.lua, it is actually a decorator
-- for the quickfix list. Because nvim-tree does not provide a way to add a custom decorator,
-- we are overriding the built-in bookmarks decorator with our own quickfix list decorator.
-- If you don't want to override the bookmarks.lua decorator, you can override a different one.
