Option: Display an icon on the omnibox
Whenever there's a text selection present, an icon on the omnibox will appear, displaying the same menues as on right click. This is optional, not by default. And I'm unsure it's worth it. This was the exact request by a user: "It would be even better if additional to right-click menu there'll be Button panel left to address field"
Search a free text directly from a search field is very useful. Chrome allows defining keywords for search engines. But if a user has ten search engines, he would not like to remember these keywords.
It is nice to have a search field like the one in firefox:

It is even nicer if we can reuse the built-in omnibox for the input of search term and provide only the dropdown search button.
