This morning I constructed a couple of extra folders inside a Mesh folder and moved some of the files from one folder to another (within the same root mesh folder). I notice that Mesh regarded this as a delete followed by an add, which meant all the files got uploaded to the cloud again (and thus they'll come down to my home desktop later). It would be nice if the situation could be recognised and avoid unnecessary transfers.
Great work guys. For a technology preview, this looks so good that many seem to be treating it like a much more finalised product than it really is. I look forward to the future.
