Matt, Anthony, deustfrr
Thank you for congratulations!
Actually 3^N appears not difficult but very boring. I found macro set that doesn’t requires search for particular cube, you only need to find a place for the cube and move it (place ;) ) to certain position and orientation. And (more difficult) sometimes you should find any cube (of the given rank) that is in wrong position (in some sense).
I see what should be done to the program more: - to highlight all stickers of the given color(s) and to lock some face (in 3 click mode) if you are going to make several twists of it. Both features seem to be very useful, at least for my method :)

Some words how I solved it:

• go from 3C to 7C
  
• first put in place all pieces belonging to the middle layer
  
• then reorient top and bottom so that have correct top/bottom color (in this stage I assign the same color - bright red - to both opposite faces)
  
• and move cubies from bottom to top, selecting position for piece by rotating top face. When finish, sort bottom pieces using one place at the top.
  
• and the orientation problem of the last piece of each rank…

Something like that. But when during 7C stage I found some misplaced 6C cubies it was not very pleasant…
