Feature/Enhancement Request | Merge the Settings and Keybindings panes in Rootless mode

[JosephLai241]

Provide Context for the New Feature or Enhancement You Would Like

There are currently two different panes that are related within Rootless mode - the current settings and the available keybindings for each mode. These panes may be toggled with the "s" and "k" keys respectively.

This makes the UI feel a little clunky; a friend suggested (thanks @LukeDSchenk) I should merge these two panes to improve the user experience.

Explain Why You Believe This Would Be a Good Feature

Everyone loves a streamlined user interface. Rootless mode already has a bit of a learning curve since it currently (beta) does not support mouse events, ie. clicks and cursor tracking. This means users will have to navigate solely by keybindings. Making it as simple as possible is in everyone's best interest.

Additional Context

The only concern I have with merging the two is displaying the keybindings for the Breadcrumbs widget:

Would it still make sense to just hit "s" when in the Breadcrumbs widget, even though "s" represents the current settings, to bring up the available keybindings for this widget?
