Mac OS 10.3.9 or better is REQUIRED.
Why? - Shadowrunner 2 relies on improvements to webkit made in 10.3.9. Several important features will not work on lower systems, making the style virtually unusable.
So, now that's all out of the way, why should you use this style?
- Smart, translucent message bubbles in black or white
- Buddy icon support, in 32x32 or 48x48 variants
- Faded message history - finally!
- Header and icon tooltips to show contact name
- Delicious background images included
