Ability to close and open "Audio clip effect editor" windows for all clips in timeline.

Please allow for an option to close all the "Audio clip effect editor" windows, so they don't keep poping up open every time I select a clip in the timeline.
This is either a persistent bug or a lack of design sensitivity. Sure, it helps having the windows open automatically when you are editing audio, but just as it can save time having them open automatically, it's also a waste of time having to close them one by one.
As it is now, if you don't have multiple monitors, you are always obstructing something else.
Maybe the windows could be stacked like all other windows.
Or maybe it can be an option in the "Window" pull-down menu at the top of the screen.
Please fix this.
