Currently the plugin only displays network speed in Kibibytes (kilobytes). While this is what users usually expect, sometimes other programs (e.g. Linphone) use Kibibits (kilobits) per second as their units of measuring download/upload speeds. It seems that the industry tends to use bits per second to measure network speed, as is done in this website: http://www.speedtest.net/ .

I would suggest that the plugin allow the use of either measurement unit, Kibibyte or Kibibit, both in the properties window when setting the bars' limits and in the panel tooltip that informs the user of current incoming/outgoing speeds.
