@lqiao2 you should get Splunk 7.1 Overview App from Splunkbase which lists out new features of Splunk 7.1 including the move towards Modern Look & Feel and Style Consistency across Splunk.
From Splunk product's perspective I would say that it gives it a consistent look and feel where Custom Splunk Apps created within Splunk will have their own Icon Color and Navigation Menu Highlight color.
Instead of Distinguishing Color from App Bar , it is now App Icon , which to me is a changed for us to get used to 🙂 Do get the Splunk 7.1 Overview app to check these out. Also, with the launch of newer versions corresponding Overview apps are also published on Splunkbase for us to check out the new features being introduced and get hands dirty to see whether they fit our needs.
