The GReader extension is for Safari 5.0 or later. I based this off of my previous GReader-Checker extension and made it to become a complete Google Reader extension.

What GReader does:

- Updates a toolbar icon when there is a new feed item in Google Reader.

- This updates you on your total unread count.

- Enables "Add to Google Reader" functionality to add an RSS feed to Google Reader when the RSS icon is clicked upon in the address bar.

- Direct feed integration into Google Reader and bypasses any hoopla needed to add the feed to your Reader.

- Adds many options for update interval from as frequent as 5 seconds to as infrequent as 1 hour.

- NEW in v2.02: GReader now switches to open Google Reader tab if open, or creates a new one if one isn't open.

- NEW in v2.03: Code optimized

- NEW in v2.04: Open GReader in current tab if on blank or Top Sites. Special thanks to Nicholas Helke (@nHenke on Twitter) for his patch.

Why should you use GReader?

- It works

- It's pretty

- It has more options than others out there

- It's even better than GReader-Checker

To do list for future GReader releases:

- Customizable Google Reader styles

- Complete integration with Google Reader

- Give the best possible user experience for Google Reader on Safari 5

- Become the most functional Google Reader extension for Safari 5
