This first video of the video series describes the various main elements of the workspace. Do not be surprised if your environment does not look exactly like this, as CircuitStudio adjusts the environment to suit the current editor you are working in. CircuitStudio uses a modern 'ribbon' style interface that should be familiar to most computer users making it easy to get started with the product.
For those fortunate enough to be using multiple monitors the interface is even more flexible that demonstrated. The panels can be moved off to a different monitor to create a larger work area focused on the document, even the document tabs can be dragged off to another monitor, great for cross probing or comparing designs.
