Thanks for our comments and suggestions--I will pass them along!
There are a few features I wanted to make sure you're aware of. We do have an option to delete multiple food items (without the page refreshing) by clicking the button towards the bottom of the tracker that says "Remove multiple food items." That will open a pop-up window that allows you to place a check next to any of the foods you want to delete and then all will be taken off at once.
If you want to change an item in a food grouping without saving the change, you can edit items after you add the grouping to your day (this process doesn't take any more steps than changing the item before you added the grouping would). Once you do add the grouping, you can click on the item you'd like to change. Similarly, clicking to delete the item and add another would take the same number of steps if it is done before the grouping is added or after.
Regarding the accuracy of nutritional items of foods entered by other members, the best thing to do is to vote on the accuracy of the item. When you click to view the item's information, there is small box on the top right of the window that asks you to verify the accuracy (or mark it is incorrect). Thanks!
