I understand, it was not ment to be a user-experience, rather a 
developer debugging option. I will probably need an option like this in 
the future to avoid searching a very long time for very old hardware, I 
will try to find an other solution for it in the future.

I will remove the 3 GRETH patches and resubmit the others.

Thanks,
Daniel
