If anyone was missing the little red highlight of feeds on the Safari dock icon – well here’s an updated version 1.1 that works with Safari v3, webkit nightlies and v4.
SafariDockStatus 1.1
The size of the unread feed count label may be controlled from the Safari menu > SafariDockStatus Preferences.
I have moved the count position towards the top of the Safari dock icon – about as far as it will go, but still allowing the count number to be scaled.
