Additional Content/Hooks

Hi,

I really like your plugin, but I miss a few customization options.

Would it be possible to add additional content sections (or hooks at least) at the marked locations? https://i.imgur.com/7zcWytx.png

Looking at the code of you plugin, I can not see any option to add additional content: https://i.imgur.com/xxRmzA4.png

Thank you,
