Hello.
I've tried to add some buttons to the visual editor (CKEditor) like spoilers or htmlbuttons for timers but i'm confused.

• Limesurvey ignore /third_party/ckeditor/config.js file
• Limesurvey make own config file /scripts/admin/ckeditor-config.js
• There is a string config.extraPlugins = "xml,ajax,limereplacementfields,codemirror"; in that file. I've tried to add new plugin to that string and make new button on the config.toolbar_inline toolbar but nothing happen.

So i need help. How i can edit limesurvey's visual editor's toolbar?
