Make it a bit more like eBay!
For example, I'd like to be able to save my favourite Google searches – and then receive email whenever Google finds a new page that matches the criteria I've selected.
An 'eBay watch' is very much like a favourite you've added to your browser. However, I'd like to see this extended – so that it's got capabilities like those found on ChangeDetection.com – bringing these together – why can't I put 'a watch' on a webpage, and then have Google email me whenever it's changed?
I'd (of course) like these under the equivalent of a 'My eBay' link, i.e., 'My Google'!

Being a programmer, I'd also like Google to treat characters like + and _ as significant.
