Developer Mode

What it does

 * You can right-click in the game window and access the Chromium developer toolbar. This helps for editing CSS.
 * Various data editors can be accessed from the main menu, including the Dialogue Editor.
 * It notices if you edit files while it's running. In particular, HTML changes should take effect after the next page reload. This makes it run noticeably slower.

How to turn it on

 * Right click on the game in your Steam library and go to Manage, Browse Local Files.
 * Double click on start_dev_mode.bat.
 * If you see a dialogue editor option on the main menu, you're in dev mode.
