Hrm, good thing you're interested in it, tho I think you should copy+paste this post of yours into
this section of the forum. Tho I will comment on em here.
a) You can go 'incognito window', a feature of Chrome, not to save any history at all. But it will save any bookmarks you make on it. You can open it by clicking the top-right wrench sign and you'll see the incognito option. Or you can just go Ctrl+Shift+N.
b) I agree, we should have it as an option. But I can see through what the designers thought while making this browser, they wanted to make it succinct.
c) You can just middle-click, even on the bookmark bar.
d) I don't think Chrome will ever get this complicated, again cos of their obvious tendency to make it succinct.
