Hi Chris.
This feature request is based on my comment in
this topic. Although you say that "This is definitely planned", I though it would be appropriate to add it here...
Basically, my suggestion would be to extend the functionality of +owner (currently restricted to windows created through the GUI command) to other non-GUI windows, such as those created by commands like FileSelectFile, FileSelectFolder, MsgBox, InputBox...
Chris could you post a reply here when this feature is available?
Thanks!
