This is going to sound sad, but the one application that I have missed the most in upgrading to Leopard is CandyBar 2. I've always been something of a customization addict, and being able to take advantage of some of the beautiful icons that artists have made over the years to make OS X look its best is something I can easily spend hours doing, productivity be damned
Fortunately for me, Panic (the guys behind Transmit and Coda) have just released the Leopard-only CandyBar 3, meaning I can now resume wasting time making my desktop look its prettiest. CandyBar 3 adds more than just Leopard compatibility - it is a pretty substantial program overhaul. Not only can system icons be changed, the dock can be now be customized too (free Icon and Dock sets available from the geniuses at Iconfactory). Additionally, Panic and Iconfactory have merged the CandyBar and the Pixadex (kind of like iTunes for your icon sets) applications together, providing icon management and customization in one package, instead of two.
From the CandyBar 3 release notes:
- Integrated CandyBar together with Pixadex with an entirely new interface
- Added large (512 x 512) icon support
- Leopard dock customization
- Additional system icons
- Quick Look integration
- More reliable system icon restoration, and much more
Now, if we can only get a Leopard-version of Shapeshifter out - I can totally optimize my interface!
