Introducing persistent searches in Gmail that are...persistent. First off, props to Mihai Parparita who did all the hard work for adding persistent searches to Gmail. I've added to Mihai's script, so that the saved searches are stored in a special Gmail contact. Previously they were stored in a cookie. The advantages are two fold:
FWIW, I hope to eventually add a few more unrelated features to Gmail via this script. For an overview of how my modifications work see my post on Cookies and Contacts.
Update: Gmail apparently changed a few things in their code this evening. I've updated one of the regex's to work with this change. If you see that your saved searches aren't being saved or restored properly, you'll want to reinstall the script.
