I am a technican. I want to see the number of results. I don't like AutoSroll. I remember the page where i find a result, so i jump to the page, with endless scroll, i did not find things again.

The sign of clicked links is a good idea.

Mark a personal favorite site in combination with my search term would be a great feature. E.g. i remember i search something about nodejs but i forgot the sitename, my browser bookmark did not help me. But when i see my old search about "nodejs" and the favorite or clicked pages, that would be a great thing.

Forget google, if somebody want to use google, he can use google. So please implement usefull functions that help people with their daily work.
