Uploaded an updated version (0.4-1) in extras-devel

This update does not bring any new functionality but it just a redesign of the GUI. I have managed to create a scrollable list for the options which will give the ability to add more options if needed as well as other functionality.

Changelog:

• Restructure of the GUI to have a scrollable list and the buttons on the right.
• Added better information messages on several actions.

I have not promoted it to the testing repo yet and since I'm away from my PC, it will hold me back for a couple of weeks (at least) in adding new features that have been already requested/discussed.

Will be good to hear your opinions on this change and more ideas for additions you'd like to see.
