Please add ability to change timestamps for multiple items at once

I frequently update my diary several hours away from my meals. If I want to have accurate timestamps, I have to manually change the time for each item. This usually isn't worth the trouble so I'll sometimes add a comment instead to let me know what time lunch or a group items was or I'll just live with inaccurate timestamps. It would be great to be able to click on the first item, then shift-click on the last item to select the group and then change the timestamp for all items at once.

Changing to the standard Windows click structure is another feature I wish you would add. (I've seen this suggested previously.) Ctrl-click to select/deselect individual items. Shift-click to select/deselect multiple items.

Many thanks, love the program!
