Child forms groups on taskbar
<p>I got an application, which has a main window, and then it open new forms.
Whole application is like a document reader with many types of sub-forms.</p>

<p>For example, I have Main window opened, 3 documet detail forms and 4 editors of other content.</p>

<p>Now. As all sub-forms are childrens of the main form, they are all grouped under one icon on taskbar, which can make a mess when you try to search for some window in list shown onhover.</p>

<p>Is it possible to tell the system, that all instances of specific form have to be grouped together in separate icon?</p>

<p>Like this</p>

<p>I got through some guides, but unfortunately, this specific problem I haven't found beeing solved anywhere yet.</p>

<p>And althrough I am looking for C# implementation here for my app design and plain preview of solution, the real application will be probably implemented in Delphi, so the true and the main question is about if the operation systems even support this behavior, because of this is a huge override of normal behavior - is it even possible to do it that way in Windows? And it is also possible to do it on Linux (gnome, kde, xfce, unity) and MacOS? For theese questions, I don't need to know HOW-TO, just if anyone hit the problem already and can point me to some solutions of articles mentioning this problem.</p>

<p>Thanks in advance.</p>
