No hotkeys, no extra steps, just rearrange the buttons on your Windows taskbar by dragging and dropping them. Allows you to rearrange your system tray icons by dragging and dropping as well (but that does require a hotkey).
No need to get all nervous when an application crashes or if you need to reboot; you can reorder your programs exactly as they were anytime by just dragging and dropping them directly within your Windows taskbar!
