Does Epic have tools like Push To Kindle for Kindle or equivalent?

Unreal Documentation is a vast and changing thing. Obviously one can use bookmarking and create folders, but what about highlighting and adding notes and flashcards? Is there an app like ‘Kindle for PC’ for Unreal Documentation? I tried using ‘Push to Kindle’ to move documents into Kindle, but this is not yet supported on ‘Kindle for PC’. It seems Epic should have some equivalent connected to the users account that allows them to add stars, highlight text, add notes, add bookmarks, search these created things, perhaps also offer an equivalent to Xray. Unreal documentation is a mutating thing so it would also need to tell the user when their various jots and highlights were not their anymore, archive the old and direct the user to the new.
