I agree.  We've been using the MR interface for xf86-video-amdgpu and
I find it awkward compared to the mailing list.  Maybe it just takes
getting used to.  I also feel less inclined to do drive by patch
review if I have to explicitly delve into the browser to look at the
outstanding MRs.  Over email, sometimes I see a patch set in my in box
that piques my interest and I find some time to review it when I might
not have otherwise if the bar were higher.

Out of curiosity what do others like about the MR interface?  How are
you using it?  What advantages does it give you over the mailing list?
 I feel like maybe I'm not using it right or missing features that
make it more useful and less awkward.  I feel like the interface makes
it harder than it needs to be to see the actual changes in MR to be
reviewed.  All of the links click through to the source view rather
than the patch view.
