2 new features requests

Hi,
I have request for 2 new features:
1. Delay JS – option to insert JS files names or Paths then the plugin will delay these files by X time (set by user) or by user interaction (Like WPRocket added / Flying Scripts plugin does)

2. Remove Unused CSS – option to remove unused CSS, I think it’s better Critical CSS, because if the page have Critical CSS created and the user got link with Anchor to middle of the page, he will see blank page/jump/FOUC.

Thank you.
