There really is nothing that is low hanging fruit, and anything that is not on the timeline just makes beta that much further away. We're focused really hard on that process of getting us to beta and the timeline that Brian posted here.
That's not to say it is a bad idea, it's a good idea, but anything that pulls us off the timeline is really likely to be put after the current TODOs to reach our goal, not before.
We already have a search update suggestion in the hopper here. Please consider adding to the existing one if it makes sense to do so, or adding a new Suggestion into the system is fine too. It makes it easier for us to find them, track them, and if necessary respond to them, if they are posted there.
