In addition to adding elements from the InsertPanel or ContextMenu, you can now simply drag the Mouse from an output point of an element to the canvas, like when drawing a line, and insert an element from the selection window. This will allow you to create models very fast and intuitively.
Step 1: Start dragging from an element end point.
Step 2: Releasing the mouse button - it will open a selection window.
Step 3a: Selecting an element by clicking on it. It will be inserted at the chosen location and automatically connected to the end point selected in step 1.
Step 3b: Clicking on the canvas without selecting an element will close the window without adding an element.
