Things I still need to do:

* Make it installable.
  - It might be easier to replace the python part with node then distribute as
    something you can `npm install -g`
* Read-line input. I should be able to up-arrow to get my last search.
* Settings file or panel for configuring colors and keys.
* Question mark should open keyboard shortcut info.
* Autocomplete? Maybe too much.
* Add duckduckgo instant results to the top of the results list.
* Look into blessed-contrib and the rest of the blessed widgets to see if
  there's anything else I could add/improve.

DONE
* Figure out why there is no visible cursor in w3m when result is opened.
  - Screen.spawn() should be showing the cursor but it's not. Tmux issue?
* Better padding so search can be used in very small terminal windows.
  - The search input scrolls when text reaches half the width...
  - Is a modal the best option for the search form?
* Search result caching.
* Return to search form from results list.
* Add numbers to the result list and allow pressing the number to open result.
* Add descriptions and possibly the url or domain part of the url to each item
  in the list.
  - I might need to use something other than the blessed list to accomplish
    this...
* Find more universal default color scheme.
