Edit metadata button request

edit metadata button brings up separate metadata window, it does not remember last used window position/size, please can you make it so that it does.

Have you seen the metadata panel that's attached to the lister?

Usage scenario involves double clicking an image to bring up the viewer, edit metadata button is on viewer, and clicking the button to see relevant infos.

The viewer also has a metadata panel. Edit > Metadata in the viewer menus opens the panel (not the separate dialog) by default.
