Debugger session resets current session context

When you start debugging it opens different session context. That
means: different file, cursor location and file list order. Now
returning back to where you were is not so easy: file list order is
gone and Ctrl+Tab doesn't help, cursor positions point to be the
beginning of files. Why it works like this? Which purpose different
debugger context is good for? When debugger is stopped it doesn't
return back to original context fully: file order is lost, some cursor
positions are not like before.
