Personally, I'd stopped the development of the IR for the moment. I know - it was voted, so just my personal opinion. But: IR is the icing on the cake, which can be done at the end. For the work would be more efficient distributed rendering, scatter plugin, proxy plugin. Because how much time it will save the IR throughout the project?
If the IR has problems now, let's get back to this later. But as I say, this is just my opinion. But on the other hand, developers should be able to do more necessary things which we are waiting too.
Otherwise, thanks for the instrument through which I do not have to be a scientist amateur :)
