Hazel 5 - Preview

I'm a big Hazel fan and a big thank you for Hazel 5...I like it.
However, I want to be sure I understand the new Preview function...because I don't like it as I currently understand it.
Can I check I have this correct:
It feels like the one thing that's a backward step for Hazel 5...that's if I understand it correctly.

However, I want to be sure I understand the new Preview function...because I don't like it as I currently understand it.
Can I check I have this correct:
- Preview is only available from a menu item or keyboard shortcut, there is no button on the rules screen as per Hazel 4?
Preview acts on all rules for the selected folder when triggered - including disabled rules, rather than the chosen rule as with Hazel 4?
Preview is painfully slow where you have a number of rules for the selected folder?
It feels like the one thing that's a backward step for Hazel 5...that's if I understand it correctly.
