Functionality is required to hide visual level filters

This is a must. Just because a field is used in a visualization, doesn't mean we want to allow it to be filtered.

The behavior of the visual level filter is somewhat confusing to me. I would expect the visual level filter to override report or page level filter or slicer or criteria set by other visuals on the page. In my particular case, I have a slicer on field [Region] and I have a visual level filter set to [Region] is "A", "B", or "C". My visual level filter does not stick when I change my slicer. I would expect it to stick as it is an override.

I agree. I don't necessarily need to filter on every item that is displayed. And if there are too many items that are displayed, then the filter list is too long and goes past the bottom of the screen.

Would be helpful if report owners had an ability to control individual level filters. It's confusing for the end user especially for instances when visual and report level filters are same.

What is the purpose of the new 'Hide Filter' option in the Desktop app if the visual filter is still present when it's deployed? Or is there a separate configuration required to enable this feature?
