  -- snacks.nvim is a plugin that contains a collection of QoL improvements.
  -- One of those plugins is called snacks-picker
  -- It is a fuzzy finder, inspired by Telescope, that comes with a lot of different
  -- things that it can fuzzy find! It's more than just a "file finder", it can search
  -- many different aspects of Neovim, your workspace, LSP, and more!
  --
  -- Two important keymaps to use while in a picker are:
  --  - Insert mode: <c-/>
  --  - Normal mode: ?
  --
  -- This opens a window that shows you all of the keymaps for the current
  -- Snacks picker. This is really useful to discover what nacks-picker can
  -- do as well as how to actually do it!
