Is there a way to customize Kentico Kontent (cloud) to add a plugin?
Requirements for the plugin:
- Can have HTML UI
 - Loads on every content item
 - Can extract text from content elements
 - Can select specific words from content item
 - Can modify specific words from content item
 
Does Kentico Kontent provide JS API for editing and modifying content in content item?
Thanks, Abhijeet
