 That's because I rewrote ca. 40% of mod2 (which is now 25% bigger), and 
because the characteristic of the change which is pretty much like a 
eye-transplantation. Because of that I decided not to put out a patch on 
the bug-tracker, and asked Dmitry when he would have time to attend the 
modification according it's dimension. So in effect I may continue 
detecting fixing and testing. Other (connected) GUI-changes from me are 
available on the bug-tracker (like the DS-details preview).
