The GReader-Checker extension for Safari 5 is based off of the work of both Victor Adrée and Alejandro JL. I combined both of their codes and implemented my own icons and settings to give the best user experience when using the extension. I based my icons off of Matt Brett’s RSS feed icon.

What GReader-Checker does:
– Updates a toolbar icon when there is a new feed item in Google Reader.
– This updates you on your total unread count.
– NEW in v1.01: Switches to already open Google Reader tab or creates a new one if there is not one open.
– NEW in v1.02: Open Google Reader in current tab if on blank or Top Sites. Special thanks to Nicholas Helke (@nHenke on Twitter) for his patch.
What GReader-Checker might do in the future:
– Allow you to pick which feeds you want to be updated.
– Enter a custom update time
Why should you use GReader-Checker?
– It works
– It’s pretty
– It has more options than others out there
