I think it would be a great idea to make it look a lot more like Chrome.
Most probably many of users are coming from Chrome, so I think it would help if it looked more like Chrome. By look I mean the layout, the positioning of the things.
Also, I know this is not the best place for it, but it makes no sense to create a folder for my imported bookmarks if I have none added manually, it just creates a folder inside my bookmarks bar, which is annoying.
