Change the layout

From CoCWiki

In game you have the option to change the default layout of your screen. This includes soldier controls, chat box, and playing view size. To do this click on View > Unlock All and then simply drag the corners of each box until you like where they are. This can make it easier to play as you can make the chat and control buttons larger and therefore easier to use during combat.

After you have them set click View > Save Layout. While in a game room you may also resize your chat screen and "Who's Connected" screen using the same methods described above. In the lobby you can also resize all of the boxes using the same methods. Remember to always save your layout, otherwise they will reset to the default. At any time you can reset your views manually by (in game) pressing ctrl+D or View > Load Default Layout or (in the lobby) by clicking Layout > Reset Layout.
