Improvements to the "Cover Flow" view

I have the following requests/suggestions/comments regarding the “Cover Flow” view:

  • It’s very slow to switch from a blank background to the actual documents, even on a 8-way Mac Pro with loads of RAM, a hardware RAID-6 and a HD 3870 (my system - I don’t know how to build a faster Mac);
  • When I do get the blurry view of the document, it takes like 5 secs to get a readable precise copy of it;
  • Web Archives show up as white documents with the Safari logo and a big “ARCHIVE” under it, instead of the actual Web Archive content; which I would expect.

edit: +95% of my documents are 72 dpi PDFs

Can you do something about it?
