Howdy, @urchindesign!
Thanks for writing in! This change to how the cursor functions is intentional. During the refresh of the UI, one thing I wanted to pay careful attention to was the HTML / CSS specs and more closely follow them as much as possible. One thing that this involved was ensuring that we were using cursors properly throughout the tool. If you review the official MDN documentation, you’ll see that pointers as cursors are reserved to indicate that something is a link. Additionally, there have been a lot of publications on this in recent years (below is just one such example):
My inclination for years has been to simply blanket apply cursor: pointer;
to anything that was “clickable,” but as that article mentions, everything is clickable on the web. The more important thing is making sure we have strong indicators present for our users to display intent. With the update, when a change has been made and it goes to the yellow “alert” state to show this, hovering over the button will give it a hover color, and I’ve also gone ahead and updated the tooltip to hopefully be even more clear on the intent of this button when interacting with it:

As the goal of the builders is to function like an analog to other desktop apps that might be used in other design disciplines, we’re trying to bring more parity between those two worlds and their conventions.
One additional change I’ve made as well is ensuring that anything that truly is a link gets the proper cursor: pointer;
style. I have added a base level style that ensure that any link with an href
will receive this style as intended.
Thanks!
