This doesn't completely work.
In constant.js I just changed the line...
editorconstant.layerdefaultstyle = "position:absolute;width:104px; height: 104px;";
...to...
editorconstant.layerdefaultstyle = "position:absolute;width:204px; height: 104px; border: 1px dotted #c1c1c1;";
... and although the width changed when creating a new floating layer the outline did not.
Any ideas?
