Not a biggie, but perhaps we could start updating the UI with small things like this.
There are boxes with links in them. When you hover the boxes, the wholebox could highlight (perhaps even with a small effect, ie gradually but quickly changing the color to a brigther hue, but that can be added any time), and clicking on the box itself would be like clicking on the link. This could work in all type of notifications where the box only has one link.
What would be nice about this is that it's even easier to click a box than the text, plus it's more game-ish.
