For a brand new browser, Chrome is quite an achievement. The features that I miss in this browser were not available in default Firefox browser either. These nifty features were largely Firefox extensions. But I miss them nevertheless.
If Chrome allowed Widgets, Plugins of some sort, it will quickly gain in features & an involved user experience. I'm sure it will become my default browser then. For now, it is my strong second browser, pushing Opera to third place.
It might be dropped because Chrome clears the cache of previously visited site. But I often need to go back 4, 5 or 8 pages quickly. Usually to click a link there.
I often need to know the expected remaining time to plan my activities.
As you can see, my wish list is small. Ofcourse, I would miss the 'web developer' extension of Firefox & 'ColorZilla'. But I do not need them often & I can always go back to Firefox whenever I need this. I need them only if I was working on layouts, and I definitely need to check in multiple browsers. So not a big issue there.
Another wish I have is that Google Chrome should soon come out with a Linux version. But I'm not expecting Google to grant this wish quickly. After all, Google Talk is still not compatible with many IMs in Linux.
