The best thing about this tool is that it's free to use, so you don't have any limitations with your usage of their service! It also has an easy-to-use interface which makes working in Data Studio even more efficient than before!! I wish there was some other features like creating new tables or graphs but overall its great as long as you know what are doing when using these tools.
Nothing really comes out negative at all here though if anything i would say maybe add filters/filters options? Maybe make them available through API calls too instead just having those limited only by dashboard access??
