Fixing the netspeed applet
Netspeed is a GNOME panel applet that shows your current upload/download speed in bytes (or bits) per second. I love it. Except... you have to manually say which network device to monitor. If you're switching between wireless and wired, this gets old really quickly. There's an option, Always monitor a connected device, but it is buggy and usually gets stuck monitoring some stupid network interface like wmaster0 or vmnet8.
