Anyone who have tried Windows Vista should be familiar with Windows gadget on the sidebar. How do we do it in Ubuntu you say?
First, open a terminal, and update your apt-get database
sudo apt-get update
And then, install gdesklets
sudo apt-get install gdesklets
After it finished installing, start gdesklets
Gdesklets icon should appear on your notification area, right click on it, and click on Manage desklets.
Add as many desklets as you want, my fave is the starterbar from Toolbar/Launcher, and it currently replaces my bottom gpanel as application shortcuts holder.
Make sure that Gdesklets is started everytime you log into your desktop by going to System>Preferences>Sessions. On Startup Programs tab, click on New, and input “gdesklets” into name and command columns. Make sure it is ticked.
…And you’re done
