If you hold down shift or ctrl when transferring gems, it transfers 5 or 10 gems at a time. This would save a lot of effort for players managing late game blood nations.

Also, when you transfer items, move the Laboratory to the top of the list rather than the bottom.

For the clams issue, I've had 100+ in a couple of games with 10-14 players and ~15 provinces per player. It is entirely possible to have to manage that many.
