The most helpful feature is that it allows you to create custom dashboards for specific needs, which makes analysis much easier than using standard reports in GA itself! It also has an easy-to use interface so anyone can start analyzing their own website traffic very quickly after installation of this tool - no coding knowledge required at all (as long as they know how to click "Install" button).
I wish there was some way we could integrate our internal analytics dashboard into one place instead having two separate tools but overall everything works smoothly together. We have used both AdWords API & DART SDKs from Microsoft and neither worked well enough or had good support when integrating them with other platforms like ours where tracking multiple channels across different websites/brands etc would be needed. With GASLITE integration however things are running smooth sailing now since its been integrated seamlessly along side webmaster console giving us full control over what's happening within.
