Reaching a usability nadir

With some parameterised operations, a few literals, and layers that return values, it was finally time to make something that resembles a program. The result was unusable to a remarkable degree. Friday ended in 20 minutes struggle with an environment offering absurdly high premature commitment, viscosity (layers can't yet be deleted or re-ordered), and poor visibility. The last is perhaps the only interesting one. All layers are visible, but it's not always easy to tell what order they are in. As Thomas observed early on (in comparison to Photoshop) I need a sub-device.
