Panels you can size
Drag the edge of the sidebar and other panels to size them, fold the report builder's columns away, and keep Halo AI open beside Settings.
Drag the edge of a panel to make it wider or narrower, and Halo remembers the size in this browser. That works for the sidebar, the side panel, the report builder's columns, the website editor's panes, the chart editor, the dataset explorer and any list beside what it opens. Each panel stays within sensible limits and gives way when another one opens. To go back to the default, double-click the edge.
With the edge focused, the arrow keys size the panel, Home and End go to its limits, and Enter goes back to the default.
More room in the report builder. Hide pages and Hide settings in the toolbar fold the columns away. See Report builder.
Halo AI beside Settings. In the report builder, Halo AI now opens at the far right as it does on every other page, so you no longer choose between it and Settings.
The website editor too. Hide blocks and Hide settings fold its panes away.
