Alternate Menu for Hplip2" extension for gnome

Introduction

This plugin supplies many useful menu's for gnome shell
the most important being the Hplip stuff.

The menu's

The "Hp Device Manager..."

This attempts to start hp-toolbox but it must be installed so please do that, if the .desktop file cannot be found it will attempt to start it in the default shell this under fedora should make the system try to install it on ubuntu it will show you how to install it.

The "Additional Printer Settings..." Menu

This submenu does nothing on Fedora just now as /usr/share/system-config-printer/system-config-printer.py does not exist; seems to be a Ubuntu/Debian thing.

The "Software Update..." Menu

This works out of the box in Ubuntu, however in other distros the update-manager.desktop will probably be missing. If so to make it work I do something like this (this works on fedora but should work on any system with Gnome)

gnome-software --mode=updates

The other menus

The remaining menus should work on any gnome-shell instalation.

Notes With History
A cross between sticky notes and a menu full of notes 🤠. You can now change the icon in the the settings. you can now move the notes in position using the ▲ and ▼ menu items or buttons in the setting page.

Files Launcher

A menu full of files to launch.

files-launcher is a menu that allows you to launch arbitrary files options are view, edit or run (if it is an executable), you can also put directories in it and then the options will be list, open in the default File Browser, or in the default shell 🤠.
