Hi @merefield,  
thanks a lot, this is already quite helpful. Just where is the best place to initialize this? Should I check in my plugin’s initializer function whether .d-editor-input element exists and hook it up accordingly, or is there a place to register the plugin as an extension to the compose view, so that it only gets loaded when the user actually opens the composer.  
Kind regards  
Alexander
