It *is* possible to run mintty under ConEmu. However, ConEmu is designed
as a wrapper around the windows console and doesn't understand Unix-style
terminals such as mintty. Therefore it runs mintty as a "graphical process",
basically reparenting its window. (You can run MS Paint in ConEmu in the
same way...). It works reasonably well, but recent builds of ConEmu exhibit
a problem with focus, moving between mintty instances with the keyboard
or mouse doesn't always move typing focus, which kinda undermines the
multi-tab approach. The problem occurs somewhere after ConEmu build
140109.

I have not tested it with the latest mintty or ConEmu though, so maybe
that problem has gone away? If you test it let us know.

As an example, this task will start 2 minttys in one tab, horizontally
split, using a theme file I have under my home directory and using
the Cygwin icon. CYGROOT is typically C:\Cygwin, of course. Note that
you need the leading ">", it is not part of email quotation!

%CYGROOT%\bin\mintty.exe -c
%USERPROFILE%\repos\dotfiles\colors\mintty-themes\SolarizedDark -
-cur_console:s1THn:C:%CYGROOT%\Cygwin.ico


Because of the focus problems I am using ConEmu less now, I tend
to use tmux (though alas, that brings in its own separate problems due
to differing terminal emulations meaning some of my Emacs keybindings
don't work, grrrr).
