If the dev was emailed, it'd also be nice to have headings for each building type since it's a miner pain when you need to quickly find one towards the bottom, indeed it always seems odd to me that so much else in the game has lots of really helpful headings, but the build list doesn't.
Our souls with high music ringing; O men! It must ever be
That we dwell in our dreaming and singing, A little apart from ye. (Arthur O'Shaughnessy 1873.)
