The ability to share to everyone in your account possibly using Domain (similar to Dynamic View).
Perhaps only allow System Admin to set this up for security.
We have an Enterprise Plan and I was looking for a method to share a sheet to everyone as viewer. We have a lot of people and creating and maintaining a group for them is too cumbersome. Publishing doesn't work, they need to be able to search the data. Dynamic View doesn't work because you can't search. Filtering is too cumbersome for this application.
