More simple requests

Pubmed, you have some good qualities. Also, some not so good ones. To wit:

--Why must the cursor automatically jump to the search field when a page loads? Like all right-thinking, i.e. keyboard-shortcut-using, people, I am a fan of using the space bar to page down. But on each new results page, the space bar just....adds space, unless I click somewhere else on the page first.

--When I type the first few letters of a recently-performed search into the search field, you bring up a helpful drop-down of my recent searches. I key down to the desired one and press Return to put it in the search box.
(a) You immediately re-run that search. Sometimes I wanted to add something else to that search term.
(b) Not only do you immediately re-run that search, for reasons beyond me you sometimes fail to run the full search term, but instead use only the fragment that I had typed in. For example, when I type in "Ph" and then key down to select "Physioprof" from the drop-down, sometimes you produce Physioprof's papers. Sometimes you produce every single goddamn paper with "ph" in it. All 8 million of them. [This is just an example, people. In reality, "physioprof" produces no search results in PubMed. Don't waste your time.]

--Select some unique author ID method and implement it. I don't care which one. But if I have to try searching for a paper by "Xu X" ever again, I will maim you.
