It would be nice to see toolbar buttons for Font size/family/color/background pickers as well as horizontal line support in the Enhanced Editor. I note these are available in the Vaadin add-on "Alump's fork of vaadin-rich-text-editor" which is also based on Quill 1.3.6. I also wondered about table insertion support and I see there has been some recent activity on the Quill Github site to include this in an upgrade to Quill 2.0.
