Visual UI Builder
Uify comes with an extensive library of customizable UI components. User interfaces are created by simply dragging components from the library to the grid-based application canvas.
Components can be resized, duplicated (CMD+D or OPTION+drag for Mac, CTRL+D or ALT+drag for Win), copy-pasted (CMD+C/V for Mac, CTRL+C/V for Win), and deleted (Backspace). Besides just using drag-and-drop to reposition components, you may also use the arrow-keys to move components in any direction, as long as no other component is in the way.
Resizing and duplicating components
In case you want to select components within another parent component (e.g. container, form, etc.), hold CMD (Mac) / CTRL (Win) while drawing the mouse selection.
