The gw2cc client in itself is extremely lightweight and by default only comes with the bare minimum of features enabled. Most of the functionality is instead provided by so-called plugins that can be activated and deactivated separately from each other. A plugin can also be an assist script you received from a developer.
Plugins are managed in the Settings menu. The Settings menu can be opened by the cogwheel icon in the upper-left corner of the screen. Make sure that you press on gw2cc’s cogwheel icon and not the one from GW2 if you run in attach mode.
To activate or deactivate a plugin, simply toggle the checkmark next to it.
Installing a third-party plugin #
Third-party plugins, for instance a combat assist script, are distributed as .pck files. Simply place the .pck file inside the plugins/ directory for the third-party plugin to show up in the Settings menu. It can then be activated/deactivated as described above.
Important: Make sure that you don’t rename the plugin file!
