It works here on Windows if the meters are set as “independent floating”, and “keep visible when switching to other applications”, which I guess you’ve tried. I have the meters outside the other app window, by reducing the size of the other app window, and the meters stay visible when switching to the other app and don’t have to be put away because they’re not on top of the other app. But maybe that’s not what you mean. Are you on Mac or Windows? Maybe if you took a screenshot.
