The sidebar is where you spend most of your time in Vessa, and it had grown a different kind of row for nearly every job. Moving between sections felt like moving between apps.
Now it has one row. Sections, the Brand tab, the library, settings and the layers inside a section all use it, so once you've learned one level you know them all. The tabs sit on a plain underline and the Brand tab opens on cards for your logo, colours and type. The header and top bar got quieter too, so your page is the loudest thing on screen.
Progress moved to a single line at the foot of the sidebar. It tells you how much of the guideline is filled in without a checklist in the way.
