// @homepageURL    https://github.com/aminomancer/uc.css.js
// @description    Makes some minor modifications to the app menu (the popup opened by clicking the hamburger button on the far right of the navbar). It adds a restart button to the app menu and it adds a separator under the "Manage Account" button in the profile/account panel. I'll continue adding more mods to this script as I think of them.
