Thanks for your work on Gerrit, Paladox!
The Polygerrit upgrade looks great; the thread view is especially amazing.
(If you are not familiar with it, check this patch [1] and click "Comment
Threads" near the bottom of the screen.) I mostly have behavior issues (on
gerrit.wikimedia.org; I haven't tested whether they affect 2.16):
* URLs are hard to get right due to arcane escaping rules. I have been
completely unable to make search shortcuts that work in both the old and
new UI.
* Almost impossible to find clone URLs. (T206049, but also in the old UI I
could click through from the patch to the to the repo admin screen and
that's also impossible to find now. I see it's slightly easier in 2.16 but
still annoying.)
* For me the most unintuitive part is the relation chain, especially when
it is nonlinear. A graph view would be handy there, and also making it more
explicit what is the parent and what is the child.
* Probably not a UI thing, but it's very annoying that patch uploaders
cannot edit the description of their own patch (the gerrit patchset
description, not the commit summary).
On the plus side,
* Avatars are really nice and make the whole experience more human. (They
are not enabled on the Wikimedia Gerrit yet, right?)
* At some point search autocomplete switched from prefix-autocompletion to
substring-autocompletion (e.g. for project names). That sounds like a small
thing but it really made life a lot more convenient.
