[Georges Basile Stavracas Neto <gbsneto src gnome org>]

commit 2301ba87d42abb1732caad2937cd01b81243ed13
Author: Georges Basile Stavracas Neto <georges stavracas gmail com>
Date:   Thu Jan 20 14:30:31 2022 -0300

    applications: Add header with app icon, name, and buttons
    
    This moves the header button into the Applications panel itself,
    and adds some fancy header information.
