Mikhail,
Welcome to Donationcoder!
That looks like a nice start of a new debugger, is it also applicable to other than C++ code?
We've been pleasantly surprised by the
BugAid debugger, a few months ago, and it seams to me you're fishing in the same lake

You have a few features different, compared to BugAid, and I hope your product gets to a similar maturity level as theirs (I have no connections whatsoever with each product, the more the merrier

), maybe it would be possible/proficient to combine the use of both!
