Super Like for this effort ! Well done Edger.
I think Sketch is very good as it but need some touches here and there and you did it pretty good.
My only concern that the tools bar here need to be more powerful (usable, obvious and reachable) like in Adobe tools. At the end we use tools from a bar to make layers in layers panel using the inspector on the right.
My problem with sketch is the tools need efforts to reach them and to customize the bar on your own use.
Anyway, I enjoyed this. Thanks.
