Do you want to watch a movie, play a song, or view a pdf with only space bar?

Who does not want?

Gloobus Preview is the application for it. You can use it both as a media player or arrange to quit on losing focus. You can use also both gtk theme and its own mac like theme. The choice is yours, i prefer gtk of course due to unity.



Installation? Easy as always.

Open terminal and add these lines;

sudo add-apt-repository ppa:gloobus-dev/gloobus-preview
sudo add-apt-repository ppa:gloobus-dev/covergloobus

sudo apt-get update && sudo apt-get install covergloobus gloobus-preview
