Currently the default is for a workspace to open with the left hand menu in view and the visualizations in the right hand 2/3rds of the screen. When creating these workspaces as a dashboard for colleagues to login and view the menu is not needed and we may also not want them to be able to move anything around.
It would be good if you can curate a version of the report that opens as a full screen without the left hand menu available. It would also be good if the dashboard can be completely locked as view only. This would allow workspace to be opened up to a wider audience who just want a dashboard they can login to each morning.
