It looks like the 'New Course'/'New Library' buttons on the studio home page.

Clicking the 'Add Component' button scrolls down to the 'Add New Component' buttons.

Admin ("Instructor") - Can edit and assign permissions to other users

I've changed Studio to catch JavaScript errors when rendering xblocks, log the error, but to then continue as normal. This means that the user is still able to interact with the xblock to delete, duplicate etc. This seems reasonable as the xblock is only rendered as a WYSIWYG representation so if it isn't fully interactive that shouldn't be a big problem.
