@blau808. Thanks for posting. I also use Joomla 3.6.4, but everything works perfectly fine on my installations. The Show/Hide Title button is a built in feature in Joomla. As developer, I have no control of whether it is there are not. It should be there for every module regardless of which module it is, or who developed the module.
Also, you should still be able to type an arbitrary position. You need to press enter after you type your text. I just tried it out, and it still works.
