This an appeal to those who would like to take part in a trial of Install Updates - the Yad version.
- Make a back up copy of /usr/scripts/updates-gui

--- End code ---
My thoughts:
- I think the progress windows look a lot nicer.
- Dialogues automatically adjust according to what text is inside aiding in readability.
- Yad allows for much more scripting options which translates to more features for our applications.
Trial will last as long as you are happy to run this version of Install Updates.
Looking forward to your feedback and opinion. :)
