Circuit Diagram 2.0 Beta 1 Released

This release includes a number of changes to make designing circuits easier, including automatic flipping of components when placing them and dragging from right to left or bottom to top. Documents can also be resized and there are many improvements to the use of keyboard shortcuts, including the ability to delete components by pressing the delete key on the keyboard.

Please see below for the full list of changes.

Circuit Diagram 1.2 Released

Custom Components
You are now able to include a component in a diagram even if Circuit Diagram does not have built-in support for it. By placing the new component titled "Custom Component" (found under the External Connection category in the toolbox), you can choose a PNG image to be displayed in your circuit diagram.

This enables you to export to PNG or print the diagram containing your custom component.

Please be aware of the following when using this feature:
