Toolbar customisation: a command's menu (right-click a toolbar button, a panel drop-down row or an S box row) pins it to the toolbar, removes it or pins it to the S box's favourites; drag buttons to reorder within and between panels (drop line); Reset Toolbar; per workspace and tab, kept with the preferences, exported and imported with the keyboard shortcuts. Workspace switcher spans the toolbar's height and opens the workspace menu (Design; the others coming later)
