Maybe we should try to get stuff into a branch asap. I don't want to hold your productivity back by reviewing the API too much, which I have probably done in this review request so far - sorry for that.

My efficiency is not the highest because i had exam today (and have next one tomorrow). Then i will have another two at the end of month. The positive side of this is that it was predicted and in some way scheduled.
All my work is on separate branch. I hope RBTool is preserving this information so that when we finally push changes - they will land in separate branch.
I expect updates tomorrow (exam ends somewhere around 12:00, then i will have somewhere around one week to next one).
