Use the Log in as vendor functionality in the top right corner of the admin panel. When an administrator with sufficient privileges does it, they get redirected to the vendor panel and can see the editing modes on the bottom toolbar.
The overall appearance has been reworked to be less overweight and clunky for a vendor, and to fit into the page without the need to scroll down.
The data for the plan was present in 4.14.2 (haven’t checked elder versions).
I do not want to get into an argument, but personally I like the new design better than the previous one. The number of data points in the order statistics is the same - days in a month, day by day.
Since you can add and remove there any blocks with any information, you can notify your vendors about upcoming changes, not just new ones. Once your vendors get acquainted with the information, they can dismiss the blocks.
I dont think its that strange, think about it from a product UI perspective. Most vendors nowadays operate from mobile. On mobile you have to scroll down a lot to get to your analytics and data points. To mitigate against this inconvenience and remove friction, vendor may dismiss as it may not be relevant right now although may not realise they dont pop up again (as is common on a lot of onboarding prompts).
Proposed solution: A pop-up at dismiss to confirm dont show this again. This is a small dev effort but actually mitigates against most use cases/edge cases and remove assumption from our roadmap
