SUMMARY Currently there are two configuration options that separately control the behavior of floating panels and docks: Appearance -> Length -> Maximum and Appearance -> Margins -> Screen Edge. This might not be so bad for configuring those floating corners if the two options took the same length unit, but they don't: one takes a percentage and the other an integer number of pixels. The reason is that the screen edge margin applies only to the screen edge the dock or panel is attached to. This makes it unnecessarily difficult to configure a floating panel or dock with a uniform horizontal and vertical distance from the screen edges. EXPECTED RESULT Either the screen edge margin should always be applied to all screen edges, or there should be a configuration option to enable this behavior. There should be no need to use two settings to configure the distance of the panel from the edge of the screen.
