Double Commander

First of all - thanks for this excellent piece of software.
I have a small suggestion: when viewing e.g. text file with internal viewer, the viewer process has the same icon as DD main window.
The same applies for built-in editor, picture viewer and, I guess, other background tasks.

This meas that when I open one file in viewer, another in editor and so on, then, when I press Alt-Tab (working mostly on Windows) I have a bunch of multiple, identical, DD icons.
Of course they have different captions, but If viewers had different icons then DD main window it would be much easier to locate it quickly.
