It would be helpful to have the ability to hide a widget from view on a dashboard when published or when viewing as not the owner/admin. For example I have a standard template for projects and a widget may not be relevant now, but I will want to use it in the future as the project matures. I would want to move it to the bottom and hide it so in the future when it was relevant I don't have to rebuild it, adjust all of the formatting, etc. to be consistent with the other dashboards. Right now I have to delete it or tell people to ignore it, neither of which are great options.
I agree as I have a similar use case. Seems like an easy fix.
