return immediately, allowing each independent thing to update itself.

not actually a view.

wrap code in an update call to ensure UI updates all at once and keybindings aren't executed till complete.

a display context only renders a view.

This contains the command log, underneath the main contexts.

only used by the one global context, purely for the sake of defining keybindings globally.

This is either the left or right 'main' contexts that appear to the right of the side contexts.

A persistent popup is one that has its own identity e.g.

this is your files, branches, commits, contexts etc.

wait until everything is done before returning.

A temporary popup is one that could be used for various things (e.g.

Binding - a keybinding mapping a key and modifier to a handler.

if you add a new mutex here be sure to instantiate it.

A guard is a decorator which checks something before executing a handler and potentially early-exits if some precondition hasn't been met.

models/views that we can refresh.
