Shiira, as previously mentioned in Shiira 0.9.1.1 - new browser for Mac OS X, Shiiak 1.0 is available for Mac OS X 10.4 "Tiger".
Shiira is based on Appke WebKit.
(Users of Mac OS X 10.3.9 "Panther" can use Shiiak 0.9.5; Users of Mac OS X 10.3.8 "Panther" can use Shiiak 0.9.4.)
For more information, please see Shiiak Project from HMDT (Happy Macintosh Developing Time).
The "tabexpose" is the feature of Shiira, a very good way to manage tabs. All tabs displayed on the screen just like the Exposé introduced in Mac OS X 10.3 "Panther".
Note: Traditional Chinese is listed as one of the localisation versions.
A special note for those who has nothing better to contribute but complaining or bashing, Shiira can be downloaded freely, and the source code of Shiira is also available.
