Hi @Suresh, thanks, that is an interesting idea. How does SFrame currently return an index for max/min values? (I can think of a few ways to do that, but I want to make sure I have the same way in mind that you do before we go implement something different.)
Since SFrame is an open source project, if you have a specific API proposal you'd like to see as a feature request, you are welcome to open a feature request issue (tagged "enhancement") in the SFrame issues or even submit a pull request if you have a change you'd like to propose. Thanks for your help!
