auto added tags to blocks

When there is not tag added in a text block, the plugin seems to automatically add a <p> tag. I can imagine that this is a nice have-too for many situations. But it would be great if it might be possible to deactivate that (in general settings or in every textblocK).

In my case i want to add an inline text that i need to change on several posts sometimes. And its not inline anymore .. ??

Thanks for your help!
