Software Center:
Synaptics is a great way to install software, but when you search for 'Text Editor' it will return a crowded list of files including terms as vague as libXYZ-dev and so on. If you get confused or irritated with that, use 'Ubuntu Software Center' under the Applications Menu. Here you can search for Full Applications only, and your search results won't be polluted with gibberish.

Manage via Terminal:
You probably already know that you can install a package (software) by typing $ sudo apt-get install <package_name>. You can also search for a package by typing $ sudo apt-cache search <Package_Name> (It will also present matches from the description), so a sample search can be sudo apt-cache search webserver.
$ sudo apt-cache show <package_name> will show basic information about the package. (apt-cache showpkg will give detailed info).
$ sudo apt-get remove <package_name> will uninstall a package, and $ sudo apt-get purge <package_name> will completely remove saved settings files and downloaded installer from your hard drive.
