editor research:
  ☐ look at simple hex editor heh: https://github.com/ndd7xv/heh
    - https://www.reddit.com/r/rust/comments/wj7wm4/media_i_created_a_rudimentary_terminal_ui_hex/
  ☐ look at editor w/ syntax highlighting Sodium: https://github.com/redox-os/sodium
  ☐ syntax highlighting video: https://youtu.be/4vw5iJMLQx0
  ☐ syntax highlighting crate: https://docs.rs/syntect/latest/syntect/
  ☐ scrolling: data buffer, cursor pos (row, col), scrolling (row offset, col offset)
    - [src](https://github.com/nazmulidris/cli-editor/blob/main/src/main.rs)
    - [viewer tutorial](https://tinyurl.com/2fdmgwxs)

    - [syntax highlighting tutorial](https://tinyurl.com/2burb3by)

text editor ex (no: save/load, undo/redo, search):
  ☐ 2 col layout w/ 2 editor components (2 separate buffers), 50% width each
  ☐ switch focus between editors, support for independent cursors (insertion points)
  ☐ minimal grapheme cluster support
  ☐ minimal syntax highlighting support (text spans)
  ☐ minimal line wrapping support (text wrapping)

more editor features:
  ☐ undo, redo
  ☐ word wrap (use `textwrap` crate?)
  ☐ syntax highlighting
    - create text span
    - figure out how to maintain cursor positions (display, raw text, ANSI formatted text?)
  ☐ markdown syntax highlighting
    - support for code block syntax highlighting
  ☐ search
  ☐ multi user cursor support
  ☐ multi user editing support

routing:
  ☐ introduce routing concept to switch between apps (with + without layout)
    - "in-app": shared state among all components, route in state? OR
    - "tmux style": have totally separate apps (each w/ separate redux stores, etc)
  ☐ build out the address book app (with routing) & use it to test out ideas

host components:
  ☐ multi select chooser (w/ option to select a single item)
  ☐ autocompletion provider

new ideas:
  ☐ flow editor (pagination / scrolling on wide screens)
  ☐ diagrams https://github.com/r3bl-org/r3bl-cmdr/issues/4
  ☐ desktop notifications https://crates.io/crates/notify-rust

mdns & p2p:
  ☐ Ideate on what this might look like
    - local service discovery
    - easy authentication (cloud auth provider login?)
