It would be nice to be able to delete hidden rows, columns and sheets - just like we can currently in the Jet Scheduler.  I have some very resource-heavy reports that I would like to move off of my local machine and onto the Jet Hub, but now I'm faced with needing to have all of these reports email to myself, so I can 'clean' them before sending on to my sales team.  This idea pairs nicely with the ability to run a 'values only' version of the report from the Jet Hub.
