As Open Office is part of the standard Ubuntu install, like other software installed as default, I have not listed it.
There are a number of must have applications needed to get the most out of Uubuntu 18.04, but first thing to do is change the deskop. Ubuntu’s standard is way too slow and reminds me of the bad old Microsoft Windows days.
The solution is the xfce4 Desktop.
sudo apt-get install xubuntu-desktop
Multimedia
VLC for watching movies
sudo apt-get install vlc
Kazam for taking screenshots and video capture of desktop
sudo apr-get install kazam
Gimp for editing images
sudo apt-get install gimp
OpenSCAD for CAD drawing
sudo add-apt-repository ppa:openscad/releases
sudo apt-get update
sudo apt-get install openscad
Development
Notepadqq – text editor
sudo add-apt-repository ppa:notepadqq-team/notepadqq
sudo apt-get update
sudo apt-get install notepadqq
