The first thing I do after updating a new install is get the applications I really 'need' to complete the install.

Unless already installed by default, I make sure to install the following...

AWN
Cairo Dock (If AWN is not available)
Docky (If AWN and Cairo Dock are not available)
Rar/Unrar
7Zip
gThumb
GIMP
Firefox
Google Chrome
Qbittorrent
Gnomebaker
VLC
SMplayer
Openshot
PiTiVi (If Openshot is not available)
DeaDBeeF
Clementine
Soundconverter
EasyTag
Audacity
LibreOffice
Abiword (If LibreOffice is not available)
