LinkPad is best described as a scratchpad for links, a scratchpad that
fills a gaping void between seeing/receiving a page link to "check
out", and eventually viewing and bookmarking the page. Simply drag a
link from your web browser to LinkPad, and drag it back out when
you're ready to view it! It's Mac-only, it's easy, and it's free, so
download it and see for yourself!
