No problem with that. I moved it to my fork https://github.com/fischeti/snitch_cluster/tree/shuffling-instr. Then we can also clean up the branch on the upstream repository.

Thanks Tim, AFAIK the commits and changes are anyways not lost even when the branch is deleted (as long as there is a closed PR).
