The software that have red dots next to them, I want to uninstall them, since I have synapse, kazam, xpad instead and the rest, I don't need. I tried software center, and synaptic and apt-get, could not locate them.
Also how to remove xfce4-terminal? I tried apt-get, but it will remove a billion library related to xfce, is it safe to remove it that way? Because I have terminator and xterm.
The "Electronic" section, I want to remove it, because it only has Arduino IDE, which is also available in the development section, thus I don't need it.
