Feature needed: Control Center and all windows sizes/places in Ubuntu Mate desktop

Control Center's window size and its position on the desktop sadly can't be remembered in Ubuntu Mate...
I feel that this is illogical and very inconvenient. This window is always assuming the same size and position after it's been closed and opened again. Very MS Windows-like behavior!
I want Ubuntu Mate to be Linux all the way!
I wish this particular window and all the Ubuntu Mate windows, like, say weather panel add-on, for example, to be not only movable and resizable, only while they remain open. The system has to remember their position and size a user had chosen after those windows were closed and opened anew!
