Not a bug.

Having using the app for 2 days, I feel like there is room for improvement about the tabs. I don't have specific ideas, maybe making more consistent with the water theme of the game. The chat is definitively not sexy. You could switch the an old-school design, with old font to make it look like diplomatic cables or go full new and trending. I just don't really enjoy this middle ground.

I'm sure you have a lot of bug fixing to do at the moment but keep this in mind.

I believe Some of that is a concession to launching the game.

For example, the chat is functional, though not full featured (hyper links etc). Every enhancement from here on is gravy.
