Hello, Miguel.

I switched departments recently and unfortunately don't have much free time
for community work. Feel free to pick up my change requests and push them
if you have time. I'll try to keep track of these changes and give some
feedback on them on occasion, but don't wait on me.
Thank you for keeping this feature in mind. I'd be glad to see it finally
used in Neutron (and any other project).


Kind regards, Yuriy.
