A problem irritating many customer employees — and sometimes even me — is that the scrollbar remains "long" and you find yourself at the bottom of an empty page when a filter is changed so that a page that was "long" before is now "short". Then the new "short" contents is often hidden at the top of the page outside the view area, which is still at the bottom of the mostly empty page, showing nothing. So the report should completely refresh and generate a "short" page in these situations.
Thank you for your great idea. While we cannot commit to a specific target version, we will consider adding it to our future internal backlog. If you can add further information about the context of this feature, please add it here so we can evaluate it more fully.
