Erik:
Working on Hide topic (I-1).
There are Gerrit patches up now about filtering out hidden, deleted and suppressed topics on board pages, and a WIP patch.
This is a big card -- lots of acceptance criteria -- so it'll take a while to work through it.
Shahyar and Erik are both working on H-8 (add hide/delete/unhide to board history) -- It may not be completely finished by the end of the sprint, but it sounds like we can release an iteration that will be a step in the right direction. We'll want to look at it on ee-flow before the code freeze next week, to make sure we don't ship something that blocks people from being able to hide and unhide.
