1. is the middle-click site-search an expected feature in the new design? If yes, it would be great to have an option/param to turn it off, because in Firefox I use middle click to open in new tab [1].
2. When I go to my homepage, the key h does not move the cursor/focus to the search edit box (if I click on some other part of the screen), however, as soon as a search is performed the h key does what is expected.
   
3. How can I cap the size of the zero-click area, or better move it to some other part.
4. What is really the advantage of a zero-click such as this one? If anyone require the binary of some character string in practice isn't it better to make the api smarter, maybe use a !bang or special character to specifically mention the intent.
   

[1] If I middle-click exactly on the URL section of the search result it is opened in new tab as expected, but if I middle click anywhere else in the rectangular box (not on the URL section but on the text snippet) a "site:website" is added to the end of my search term.
