Hi Michael,

You often say that styles itself doesn't have a visible/hidden state. But considering this...
Let's say there is a style Blue with some objects that belong to it and those objects are all hidden (Blue style has no eye icon). Now I activate a style other than Blue and draw an object. Then select this new created one and assign it to Blue style by left-click on (blue) swatch - object disappears! But it shouldn't because I don't assign hidden status to that object, I only "move" it to the Blue style. Note that it doesn't happen if there is at least one visible object in the Blue style (half eye icon).
Since the hidden state of object was inherited from Style, it is something I consider to be a bug.
