Add customization to CKEditor for specific H5P plugin
we´re using the h5p-php-editor & h5p-php-library on a not official supported platform. I would like to override the CKEditor configuration to allow more html elements and add some new buttons to the toolbar for a specific plugin (Image Hotspot). But currently I don´t see the point were to start. I guess I have to repack some H5P library´s, but which one?
It seems that every plugin includes it´s own configuration for the CKEditor, but haven´t found yet where. Could someone please point me in the right direction?
