Hello - How do I find graphical utililities for the Ubuntu 13.1 desktop environment that replicate things like Console and Activity monitor on a Mac. Also looking for utlitilites for Proccess Start/Stop like you have in Centos. Looking to make Ubuntu as similar graphically as a Mac (or ugh Windoze).

Also how do I know what tools in /usr/bin are actually graphic utilies that I can run/pin to the taskbar.

Thanks for any help!
