The ability to save filter settings that are used frequently within Site Explorer and Keyword Explorer, i.e. in Site Explorer>keywords, I filter to show only keywords in positions 8-30, with volume greater than 20, to show keywords that I am on the second or third pages for, and therefore that i could improve my content for. If I could save that filter view as a preset it would save me 5 seconds x 250 searches/day x 250 days/year = about 85 hours per year... it adds up!
