ReSharper 10.0.2 / VS 2015 Update 1 - Test Runner issues

Just upgraded our stack to R# 10.0.2 with VS 2015 Update 1.

It's a minor niggle, but the test runner updates very, very slowly now while tests are in progress, in large batches rather than one test at a time.

Is this the expected behavior? If it is can I tweak it so that it works like it did in all prior versions of ReSharper, ie, update the UI immediately?

Another minor niggle, the tree layout in prior versions used to follow the project structure verbatim from the Solution Explorer (ie, alphabetical order), but now it's in a seemingly random order which I can't change, which makes it very hard to find specific tests in the tree in a large test suite.

I've tried all the Group By options in the runner but none of them give me back the structure I want.
