Is there a plan for how floating dialogs should be managed with multiple windows ?

Currently each document has is own set of dialogs and a dialog-manager to control them.
The dialog-manager ensures there is only one instance of each dialog per document.
So with 2 documents open, you have 2 dialog-managers and can have 2 identical dialogs floating around at the same time (and several bug reports relating to this below)
All floating dialogs respond to the current active document.
When a document is closed all the dialogs opened with that window are reattached to the next open window and remain alive until the application is shutdown.
Hence memory usage grows for each new window that is opened and is not reclaimed when documents are closed.


Users have requested 2 different styles of operation

(1) Have floating dialogs per document, but close/hide them when a document is closed/unfocused (258013)

(2) Have at most a single instance of each floating dialog that works across all open documents "gimp style" (317439).


Which is the preferred behaivour ?

(1) Looks simpler because (2) needs to deal with dialogs docked with a document and floating dialogs across the whole app, and with new instances launched (such as double clicking a file in the file manager)
