As a user, while navigating on a Node Document. I can see and edit existing terms within the document. However, as stated in this issue, large document crashes the JavaScript main thread. The number of characters where it happends is depending on the user computer RAM.

New feature proposal (mvp):

• when a limit of characters is reached, add a read safe mode
• in this mode, cannot edit/add ngrams
• display a UI feedback to the user explaining why the feature is not available
