The Home page hides the open design, yet Save, Undo, Redo, File › Insert,
Save As and Export, and the design's keyboard shortcuts (Ctrl+S/Z/Y,
Delete, V, F2, F6, Esc, S and tool keys such as E) still acted on it:
Delete removed the selected body unseen, Save wrote a design the user
could not see, and tool keys left Home without being asked to.
On Home the top bar's Save, Undo and Redo are dimmed with a translated
"open a design first" tooltip, the File menu's design items are greyed
out, and only New, Open and Preferences keep their shortcuts. Everything
works as before once Home is closed.
