1) Clearing all can waste server CPU when other pages are OK and you only want to update one. Please add clearing cache for one page only.

2) Feedback of progress: Please list somewhere the pages that are currently cached, when they were cached, and the progress of caching process when in progress.

3) Preload based on sitemap.xml page from SEO Framework / Yoast.
