I have to admit that I just ignored the “Try new experience” button that has been at the top right of the screen for months already… I only used the new experience when I had some spare time to explore what’s new, but if this wasn’t forced to me, I may never use it for real.
Also, I avoided it as much as I could because when I switched to the new experience the navigation bar at the top changed to the mobile hamburger menu and it was almost impossible to use in a wide screen. I usually need to get my stuff done instead of dealing with bugs so I just tried to avoid it as much as I could, but now that it’s deployed in Sandbox I think it’s not a problem anymore.
The responsive design applied to this new layout makes better use of the screen space (I don’t need to scroll that much down and then up when looking at attributes down the page). I agree that new grid layout looks like it doesn’t respect the alphabetical order of the attributes (they’re sorted but displayed in 1-4 columns horizontally and the overflow goes to the next row), but I was already using Ctrl-F to search for attributes in the page because some attributes were lost in the long scrollable list anyway, and now label and value are one on top of the other, so it’s easier for me to find the info I need.
The only thing I’m still digesting is the need for “Access” and “Accounts” tabs. They provide different level of detail of the same things, and we may end using “Accounts” more than “Access” because the later only references sources and not the accounts associated to access profiles and entitlements, and we have people with multiple accounts in our sources. But clearly the “Access” tab is much better than the “Roles” tab in the old UI.
All in all, this is just a matter of getting used to the new experience and finding ways to get the most value from it. Customers of a SaaS product can only influence with feedback on the new features, but at the end the company that owns the system takes the decisions on what’s implemented and when it’s deployed to customers.
