In Opera we have 5 tabs, (14 tabs under the advanced tab), that makes: 5+14 -1
= 18 tabs with options to configure.
In Chrome (Beta 0.2.149.29) we have 3 Tabs with options to configure.
Maybe the Google Chrome Team adds more oft them later, but the essence is:
The Usability team has researched how the browser should work and behave,
all settings that makes sense to configure are there.
No options the users doesn't care about!
And that follows the 2nd major usability rule from Joel.
Yes, i like them a lot!! :-)
Every time you provide an option, you're asking the user to make a decision.
Chrome is the browser release from Google, based on Chromium. Chromium is the open source project.
