Watch My Domains SED v4 is getting another update which includes a new monitoring module. Other additions include additional themes, ability to update the application using the command-line tool even when installed into non-standard folders, etc.
Here are somesneak peaks of the new module.
The new monitoring module makes it very easy to manage domain portfolios that are not extremely huge. You can use it to quickly view snapshot views of your domains without having to scroll through large spreadsheet like domain lists. The monitoring module can be used to track both domain expiry dates and SSL certificates.
