I thought of making the interface look bigger by merging the chat window into the same game's window and have it on the left side. It didn't look as good at first but then I've got this idea of making the menu screen and certain interactions appear on the left as well, for example, opening up your bag or the game's map would show up above the chat; here are some screenshots.
Let me know which one you prefer, and if you have any suggestions, please let me know!
