Enter to open address in new tab
Following this rather older topic - user moving from Maxthon browser here. One of main things that makes me hesitate is inability to open address in new tab automatically after hitting enter. Really got used to this and doing that automatically expecting new address will not overwrite current page.
Second thingy that is right next to this in options - Domain expansion feature - would be nice if there are 2 or more options like Ctrl+Enter will expand to xx domain, another shortcut will expand to xyz domain etc... Useful especially for users using both lot of nationally specific domains and .com domains..
