Togglable Bar at Runtime?

[ZaheenJ]

Is your feature request related to a problem? Please describe

Is there any way to enable and disable the bar at runtime assuming is is enabled in the config? Something like a key binding to be able to disable the bar and reclaim that space for the layout but reenable it when you want to.

Describe the change / addition you'd like to see made

Ideally I want to be able to do something like this:

let key_bindings = gen_keybindings! {
        ...
        "M-S-b" => run_internal!(toggle_bar);
        ...
}

Describe alternatives you've considered

Couldn't think of any other than just permanently disabling or enabling the bar.
