Copy, cut and paste, even between circuits. • Copy or cut a selection and paste it wherever you like, even into another circuit. The wires inside it come along. • On iPhone, the bottom bar now holds Select, Select multiple and the Insert and Edit menus, and a trash appears as soon as something is selected. On iPad, the toolbar gathers the same actions and no longer runs off the screen in portrait. • Press and hold a selected component to rotate, duplicate, copy, cut or delete the whole selection. With a keyboard, ⌘C, ⌘X, ⌘V and ⌘D work too. • Ohmira, our analog electronics simulator, is now on the App Store.
