Help to modify kangaroo.exe code

I am not expert with c++ (sorry it is very hard to learn normal user I am not programmer)

I think I would like to add command to call function Save to function output

I am not sure it correct or not

Kangaroo::SaveWork

bool Kangaroo::Output

I see at Kangaroo::Output function works two thing one open file output and write private key to output file  and then print out treport on display show message found private key

So, if I add function SaveWork to work before write output file (or after write output file but before print out on scree to show private key message)
may be help to save work file include  collision point

may be function SaveWork , process only on schedule time

and more one collision point to show when fprint show hex private key (when found)
how I can fprint this value when found it


Total I want to modify 2 thing
1. write save file again when write output file
2. print out collision point

I think insert code may be simple, anyone can help?

Thank you for help
