The name field of the properties of a subflow has a fixed length no matter the width of the properties window is. This is annoying when having long property names. Solution: scale the name field to the property with the widest name field. Or at least increase it when the window is resized in the width direction.
In css...
propertyWindow: { width: 100%; }
propertyName: { width: 30%; float:left; }
property value: { widtj: 95%; float right; }
my first contribution .... don't be to harsh
