Very Cool, Recomended

I wanted something to show me real time internet speeds on the top menu bar. It does that along with battery status and how much data you've uploaded /downloaded. There is also a nice display of your Hard Drive space. Internet Speeds are shown in bytes so you may have to multiply this data by 8 so it corresponds with many Speed Test apps that use Mbps (megabits) instead of MB (megabytes.) Wishlist: a log file to show how often my wifi connection connects/disconnects/reconnects.
