Trying to solve the issue where an editor is updating content and gets timed out. When they log back in they lost changes. I know you can increase that time out, but can you implement auto save? Assuming they are using best practices and version the content before editing so they can get back changes if needed. I found this, but it is out of date and download link doesn't work. http://sitecoregadgets.blogspot.com/2011/11/rich-text-auto-save.html
Thanks!
