package gui

// A window refers to a place on the screen which can hold one or more views.
// A view is a box that renders content, and within a window only one view will
// appear at a time. When a view appears within a window, it occupies the whole
// space. Right now most windows are 1:1 with views, except for commitFiles which
// is a view belonging to the 'commits' window, alongside the 'commits' view.
