Changes from 6.4 to 7.0

Hi DevTeam,
I do not know if it's the right place to discuss it but the new filter option of "Acknowledeg" could be a nice addiction if it's also clear where we need to "Acknowledeg" a problem.
On Zabbix 7.0 Alpha2 the old link for "Ack" it's change in "update", for a new user I think it's not so intuitive.

Also, on the "Update" modal view everything it's "flatted" and it's not so easy to find the "Acknowledeg" option.

Could be nice to see some Highlight for the most important features on this specific modal view.

Thanks so much

dimitri.bellini, the Update button was added in 6.4 with the purpose of making the UI easier and more accessible for new users (see ZBXNEXT-7605). It was difficult to explain that the user needed to press Ack to change the severity or suppress the problem. The current pattern, I believe, resolved the long-standing UI inconsistency that seemed natural to old-timers but was confusing to everyone else.

And while I agree that Acknowledge is important for the workflow, we don't have a common UI pattern that visualizes the degree of importance. If we ever introduce such a notion, this should be utilized across the entire UI. But we should be careful with such patterns because promoting our opinionated feature importance rankings to users with contradicting habits can provoke some unnecessary debates or more confusion.

Hi Alex,
and thanks for the feedback.
My consideration it comes from as you already mention "long-standing UI inconsistency" and in this specific case the introduction of the filter for "Ack" it's a step forward for more "inconsistency"

How a new user is able to correlate "Ack" with "Update"?

I would suggest to start to think about to "UI pattern that visualizes the degree of importance", at least a first implementation.

Thanks so much
