COMPATIBILITY
-------------
1. This plugin has been created for the standard version of Roundcube as provided on the Roundcube website:
   https://roundcube.net. It might not work properly with customized versions of Roundcube including the version
   provided as part of the Kolab system. Please note that we cannot provide any technical support for the plugin
   deployed on a non-standard version of Roundcube.

2. This plugin will work with the 'larry' and 'elastic' skins, but due to the limitations of those skins, some content
   boxes will not be transparent and some options might not be available. For best results we recommend using one of the
   Roundcube Plus skins.

3. For the automatic text color detection, the GC image library must be installed on the server.
