Custom Tooltips for GNOME Shell Panel Launchers

Visually and interactively it no longer competes with other desktops or devices for the hearts and minds of users. The GNOME 3 Shell has a modern visually attractive and easy to use user interface (UI) that is more akin to that of an IPad or a smart mobile phone. It provides the key interface functions like switching windows, listing and launching applications,
