Problem: despite being optional, the infobox is a great summary tool. And there is a huge list due to the diversity of topics in the encyclopedia.
Proposed solution: Or having a button with a list of infoboxes to add quickly, or when creating a new article the assistant suggests a related infobox; for example: article biographies, biography infobox. In addition to adding the option to hide the infobox, this is good on mobile.
