I'm ok with porting my pull requests over, but I'd really like it if we could merge in the pull requests from Weiguang Cui:
https://bitbucket.org/yt_analysis/yt/pull-requests/2534 (Gadget I/O improvements) https://bitbucket.org/yt_analysis/yt/pull-requests/2560 (docs for PR 2534)
and Andrew Myers:
https://bitbucket.org/yt_analysis/yt/pull-requests/2575 (support for face-centered fields in the AMRex frontend)
I realize that both of these PRs are quite frontend-specific and that not everyone will feel comfortable reviewing, but it would be helpful if you could step out of your comfort zone and give it a shot. I'm personally of the opinion that both of these efforts are mergeable as-is.
If others feel that we shouldn't rush these through that's ok, I'm just worried about these in particular because they've been open for a while and haven't seen sufficient code review.
