Segments get a visual builder with a live preview

Building a segment used to mean filling in a form and hoping you'd described the right people. Now it's a canvas. You add conditions as chips, group them, and a sentence underneath reads your rule back in plain language.

The part that changes how it feels: a Members preview updates while you build. You see who matches before you save, not after you send.

Segment detail pages also picked up a Used in panel, so before you widen or narrow a segment you can see which campaigns and automations are leaning on it. The preview and the counts refresh on their own while the page is open.
