Thank you so much for the thoughtful feedback — and welcome to the world of add-ons!
You're absolutely right: at the moment, the blocking is intentionally soft and non-intrusive — it's meant to support self-control, not force it.
That said, you're not alone in wanting a stricter mode, and I'm currently thinking through how to implement a "harder to disable" version for those who want stronger boundaries. Stay tuned, and thanks again for the great suggestion!
