There's one piece of information that I would really like to know for each journal but which, as far as I can see, is not (yet) made available:
Time to rejection.
Many journals publish details of the breakdown between submission and publication, but as far as CV points are concerned then once it's accepted then I don't care how long it takes to get actually published. But if, for the sake of argument, we accept that I want to get my article into a high-ranked journal but have time constraints (for example, if I'm looking for a job) then "time to rejection" is the most important piece of information that I can think of. Knowing that, I would submit first to a slightly higher ranking journal than I really thought it should go to knowing that I had enough time to get it into a "safe" bet if they rejected it.
