WME shows two kinds of closures:
- effective closures, affecting routing and visible on livemap
- suggested closures, non affecting routing and not visible on livemap. Those suggested closures always have a duration equal to a multiple of 24 hours, starting and ending at the same time of day (on different days, obviously), and are usually created by editors having a layer lower than 3. Those suggested closures result from closure reports made from the app.
The WME displays both kind of closures using exact same visuals: it is necessary to open and examine the closure, to determine if it is effective or suggested.
I suggest enhancing the WME to allow visually identifying the type of closure.
