This might be useful for those with Kindle ereaders, who also use the “higlights” feature: the free Bookcision gives you a file of your “highlights” that you can safely archive on your desktop PC.
If, like me, you have a trillion Instapaper editions lingering as useless ghost files in your Kindle 3’s “Archived Items” folder, it’s annoying that you can only delete them one by one. You need a Bulk Delete option, which Amazon doesn’t provide. Pepa’s Check and Delete to the rescue! It works perfectly, as a simple browser bookmarklet.
