Added:
  - [aerial.nvim](https://github.com/stevearc/aerial.nvim)
  - [better-escape.nvim](https://github.com/max397574/better-escape.nvim)
  - [dressing.nvim](https://github.com/stevearc/dressing.nvim)
  - [ident-blankline.nvim](https://github.com/lukas-reineke/indent-blankline.nvim)
  - [nvim-notify](https://github.com/rcarriga/nvim-notify)
  - [todo-comments.nvim](https://github.com/folke/todo-comments.nvim)

Moved plugin source from Github to Nix:
  - [Comment.nvim](https://github.com/numToStr/Comment.nvim)
  - [neo-tree.nvim](https://github.com/numToStr/Comment.nvim)

Mapped windown switching to `<C-h`... instead of `<M-h`...
Moved some coliding lsp keymaps under the `<leader>l` group
  - Eg. `<leader>ls` for signature help
