Re: Contextual menu font-size
The font size matches up exactly with the font size of other contextual menus (such as right-clicking an item on the desktop).

Re: Review link
Being looked at.

Re: Arrows
Currently, there's no way. We had planned to have a new window that would show the other results, but we didn't have the time to do it before 4.0.

Re: Tooltip
Lots of people disliked having the tooltip pop up for every result. It's only shown now if there's metadata.

Re: Filter on what's new
Will be there before 4.0.

Re: selections
If an item came in that matched an existing result it will get grouped into that result & raise it's # count. If that happens to move the line up or down (to keep the sorting in order) AND that line was previously selected, then only that line will keep the selection (even if other things were selected). This is necessary (although the behaviour could be improved) because of some bugs with row selection in Java that extend the selection when new results are added or move around.
