I've tested this version today, and I needed this patch to make it work on top of v4.20: http://code.bulix.org/9o8fw5-503690?raw Once that patch applied, my tests were working as expected. If that make sense, could you resubmit a new version with these merged so that we can try to target 4.21? Thanks!
