Thanks for raising this!

I have a feeling this should be in master now, but master is outdated as well.
I'm waiting for some more details in #362 before I can fix branch updates.

Updated master and latest seems to include functionality from this branch:

I'm assuming this to be resolved, but please let me know if that is not enough.
