Issue
Explicit labels - The select input (drop down menu) for the "Add a block" section has no label associated to it.
Title attributes - The select input (drop down menu) for the "Add a block" section has no title attribute associated to it. Given the organization of the interface, using a title attribute with a value of "Add a block" would be helpful to non-sighted users.
