I like how easy it is when creating reports or looking at previous activity/transactions in our system with this tool! It's very helpful because we have been able solve many issues throughout time by just searching through old transactions using different filters such as "Date range" etc..
sometimes there are times where you can't find something but if your familiar enough with what search terms work best then usually they will bring up results even though its not exactly right (but close). Sometimes certain fields aren;t available until later versions of sales cloud which makes things more difficult than necessary since some people don'y know about those upgrades yet so having these options would be great!!
