Give each project its own space with named, colored tab groups in the sidebar and top tab bar. Nest groups for larger projects, drag one tab onto another to create a group, and move sibling groups up or down from their menu. Trace Explorer opens on the right. Move it to the bottom, resize it, or detach it into a separate window. This update also improves workspace recovery, preserves useful backups through repeated saves, prevents pending sleep from closing a reactivated tab, and improves pane stability through zoom and restore.
