A new feature in Gmail allows you to send attachments while you are using Gmail offline. Well, not actually send an attachment since you are off line, but attach it to be sent as soon as you find your next internet connection. It is a simple improvement, but a great one.
"One of the most requested features for Offline Gmail has been the ability to include attachments in messages composed while offline. Starting today, attachments work just the way you would expect them to whether you are online or offline (with the exception that when you're offline you won't be able to include inline images). Just add the attachment and send your message.
If you have Offline Gmail enabled, you'll notice that all your mail now goes through the outbox, regardless of whether you're online or offline. This allows Gmail to capture all attachments, even if you suddenly get disconnected from network. If you're online, your mail will quickly be sent along to its destination."
Speaking of simple but great improvements, Google Reader now has Favicon support.
"One of the more popular suggestions was adding favicon support for subscriptions, so today we're introducing just that (thanks to 20%-er Shreyas Desai).
We realize that not everyone wants their subscription list to turn into a multi-colored extravaganza, so we've made it into a setting that you can access from your subscriptions menu."
