OpenRCT2 Park Message Manager
This plugin for OpenRCT2 allows you to managed the messages in the park. You can delete a single message or all the messages at once. You can also add new messages of different types.

You can also select the colour of the text (which will also be previewed in the dropdown box).
Download the sourcecode release or the .js file from this repository. Copy the ParkMessageManager.js file to your OpenRCT2\plugin folder. In game click the park map menu item, there you will see the option "Manage Park Messages".
