Plugin variations - subplugins that are created inside the origin plugin for the following purposes:
Starting from version 8.1, plugins can create not only multiple windows, but also multiple left panels.
Let’s have a look at the Translation plugin. The plugin itself does not need a visual window for translation as it can be done just pressing a single button, but its settings (the translation direction) and an About window must be visual. So we will need to have at least two plugin variations (translation itself and settings), or three, in case we want to add an About window with the information about the plugin and its authors or the software used for the plugin creation.
To create plugin variations, you need to specify its parameters in the config.json file and build the index.html files for each variation.
