Move all legacy tray icons to the top panel
Many applications, such as chat clients, downloaders, and some media players, are meant to run long-term in the background even after you close their window. These applications remain accessible by adding an icon to the GNOME Shell Legacy Tray. However, the Legacy Tray is hidden until you push your mouse into the lower-left of the screen and click on the small tab that appears. TopIcons Plus brings all icons back to the top panel, so that it's easier to keep track of apps running in the background. You also get some options to control the look and feel: You can leave the icons in full color, or dynamically convert them to grayscale, etc.
