First off, love the game. I know it's beta and you're still working things out, so, a suggestion...
When I'm trying to trade with someone else and get the best deal possible, it's often very difficult to see the trade meter as I add/remove things. Perhaps changing the color schemes a bit or putting a black border around it would make it easier? Not sure what the best solution is, but it's very difficult with certain races to see the meter moving at all.
Thanks!
Edit: Playing the drath and trading with the Onyx is particularly rough.
