Suggestions: Target Nearest & Mouse Control

Loving Guild Wars, thanks Arena-Net, but there are a couple of things that bug me slightly:

1) I don't know whether this is just me but I find the "Target Next" action annoying, half of the time it is fine but half of the time it targets someone right on the edge of your compass rather than in the group you are currently fighting. I would suggest that the "Target Next" keeps the default key of "]" but the "Tab" is moved to a new action, "Target Nearest", which as the name suggests targets the nearest opponent.

2) I think it would be really useful to be able to assign actions to unused mouse keys. I have a Logitech MX-700 and would love to be able to use the Back and Forward thumb buttons to do "Target Next" and "Target Previous" and to be able to use the third button (on the scroll wheel) for the above "Target Nearest" action.

What does everyone else think?

Target nearest is 'C'

How did I miss that! I have looked through control options a number of times! Thanks a lot!
