Plugin Manager
The Plugin Manager is where you can edit settings for any plugins which have been designed with a config.html file and a web worker. If you see a plugin in the list but nothing appears when you click on it, then that plugin is probably using some more basic functionality and cannot be edited live inside Selectoplasm. In those cases, you will need to edit their files and reload your app.
For plugins that do have a dynamic interface, however, here's how it works.
The plugin's configuration settings will appear on the right of the plugin list. These are set by the plugin and dynamically generated by Selectoplasm. Most inputs are fairly straightforward. If the plugin uses a dynamic list, you can edit the list using the settings button on the top right. This will allow you to add/remove list items, as well as reorder them.
You can also reset the config to the plugin's defaults, and toggle the preview on and off.
