  # TODO: Check out these plugins as additions / replacements:

  # - https://github.com/glacambre/firenvim Give it another try, integrates neovim into firefox
  # - https://github.com/sindrets/diffview.nvim/ 

  # - https://github.com/weilbith/nvim-code-action-menu/ Check again in future, right now not of much useness on my setup.
  #
  # Alternatives:
  # - https://github.com/mfussenegger/nvim-dap Alternative to Vdebug, more modern and should work with firefox as well? But needs node …)
  # - https://github.com/nvim-neo-tree/neo-tree.nvim (General tree, not only filesystem, alternative to nerdtree but can also be used for buffers etc.)
  # - https://github.com/simrat39/symbols-outline.nvim/ Replacement for tagbar using lsp, combine with https://github.com/jose-elias-alvarez/null-ls.nvim once it supports Workspace Symbols / Document Symbol
