I would like to hide in the Home Dashboard the panel plugin on the right and have the dashboard plugin use 100% of the width.
Please can you kindly guide me on how to do that?
Use the settings menu an Save As to create a copy of the home dashboard. Then modify it to your liking then save it AND START it.
You can now go to Org or profile preferences and change your home dashboard to your custom home dashboard.
That worked just fine.
Thanks @torkel for the guidance
