It would be nice if we had a global filter that we can apply to all the views. You could have the option of having a filter per view as it is, but another feature of a global filter that affects all views.
My use case is an editorial calendar with multiple sites. I still need the individual views to have different filters, but it would be nice to have a global filter to only show one website I am working on, while going to each view.
This would be an easy, yet very useful feature. One that probably a lot of people wouldn’t realize how useful it is until they tried it.
