The only thing that might make things go faster, IMO, would be the capability to combine foods into a meal and then enter that meal. AND YET, if it's a complicated meal, it's still going to be complicated. There just aren't that many short cuts that would serve everybody every time.
I think the 'recent foods' makes logging go more quickly. People do tend to eat what they ate before, especially if you utilize leftovers. Also, if you buy a pound of apples, for example, you know you're going to be going back to enter that - or past salad - or low-fat chips.
There are so many trade-offs. All in all, I like fitday's logging better than most other websites' but I may be biased. I have so many custom foods already entered.
