The Ubuntu 11.04 (Natty Narwhal) operating system introduced a different user interface, designed by Canonical, called Unity. The default indicators are nice, but many people complained that they miss their usual applets on the panel.
CPU monitors, system load indicators, bandwidth statistics, weather indicators, RSS news feeds, DropBox handlers, and many more other applets can be quite easily installed on Ubuntu 11.04.
This article will show a list of ten most used Unity indicators (panel applets), with installation instructions and screenshots. At the end of the article we will also list other indicators, less important, and where to find them.
1. Weather Indicator
This is the most easy to install indicator, as it is provided in the default Ubuntu repositories. Just open Synaptic or Ubuntu Software Center, search for weather-indicator and install it. Log out of your current sesssion, log back in and you'll find it on the panel. Set it up and it will work like a charm!
