add apps to top panel in ubuntu 12.04

Solution 1:

If you are using GNOME panel then you can add any application in there. All you have to do is Super+Alt+Right Click in panel. Click Add to panel and then select Application Launcher and click forward.

Then choose your desired application from list and click add.

You are done.

Solution 2:

You might want to pose the two questions as two different ones. As for adding an app in the top panel, if you are using Gnome classic, you can simply drag the specific app from the drop down menu under "applications" onto the top panel.

To see the processes, you can choose "system monitor" from under application -> system tools.
