When I am in a program window and open some files, they can be opened in one window, on some cards/panels. But when trying to open a file, dragging it eg. from TotalCmd, and droping on exesting window of KompoZer, this file is opened in new window. The same while opening a file from Windows system "Send To" or doubleclicking a file in commander. Could be in KompoZer so, to be allowed working like in described cases? E.g. as a parameter of commandline, or option in preferences like checkbox "work only with 1 window", or feeling drag&drop on window or panel.
