I can certainly do all of those things, and do, but I'm becoming a more
skilled gerrit user. My concern is about new contributors, who have not
learned gerrit or who have not learned the way we have customized our
use of gerrit. Throwing away their work because they've been away for
some period of time (think extended vacation, illness, family emergency)
is hostile. The patch is already in a state that would prevent it from
merging, no? So if it we can hide it from reviewers that don't want to
see those sorts of patches, without being hostile and without hiding it
from *all* reviewers, that seems better than automatically discarding

Does the default dashboard we have not seem sensible for a new
contributor? When I'm logged in it shows me all of my open changes (this
is where abandoning a change makes it "disappear") and reviews where
I've commented. A slightly more advanced user can star changes and see
all of them in a view, and watch projects and see their open changes.
More advanced users can query by project or status, and even more
advanced users can bookmark those queries or even install dashboards
We have different types of users, who will want different things from
gerrit. I don't think we want the default view to match some sort of
expert view, but we should make it easier for users to do more with the
tool as they gain more experience.

I don't think every reviewer needs to be looking at the same view, so I
don't think maintaining consistency is a problem. To share that Oslo
dashboard, we have a link in the wiki and we keep it up to date by
managing the dashboard creator input file. It doesn't change often
(usually only when we start graduating a new library) so it's not a lot

We should be focusing on maximizing the ability of reviewers to find the
patches they do want to review, rather than ensuring that everyone is
reviewing the same thing. So far I have only seen discussion of
abandoning patches that wouldn't merge anyway. Reviewers who come across
those patches will see the -1 from jenkins or the -2 from a core
reviewer and either understand that means they should skip reviewing it
or waste a small amount of their time until they do learn that. Either
way reviewers who want to ignore the patch by using a filter query will
be able to continue to do that.
