Can the position of the child windows be saved relative to the parent window?

I'm not sure if this is the right place for this...

mp3tag saves the location of child windows (like search and stuff) and reuses the location if the window is reopened, which is great, but I think it could be even better if it'd save the location relative to the main window.
I use several monitors and whenever I move mp3tag to a different monitor (which happens quite often) all the child windows pop up in the old location, which is on a different monitor which I just moved mp3tag away from because I need it for other things. Additionally I have to move every type of child window seperately because they all retain their positions independently (which, again, is great if you don't move the main window around much).

thanks for reading
