This application gets better with each update, but I don't like many of the interface things:

1. The preferences do not have a good layout
2. The Krypton panel is rather ugly
3. The buttons (toolbar, preferences, etc.) are kind of gross
4. I don't like brushed metal
5. Do not make the URL field look like a search bar!!! Rounded is not attractive...
6. And more...

Here's a thought: make it look like a unified version of Safari. Give it a smart, uncluttered, look and feel. It makes me think I'm in some sort of a Cocoa maze. Take the preferences and downloader, for instance: they don't have much content, therefore they should be small panels. Also, I wouldn't use utility panels. Not good!

Another thing, the whole goal of Mac OS X is "you know one program, you know all". Your keyboard shortcuts should match Safari. Apple made them what they are for a reason:

Page bigger: ⌘+
Page smaller: ⌘-
Page normal size: ⌘0
Back: ⌘[
Forward: ⌘]
Home: ⌘⇧H
View source: ⌥⌘U
Reload page: ⌘R
Stop: ⌘.
Downloads (Krypton): ⌥⌘L

Clean up the interface and then this is a GOOD web browser.
