Great tip. I'm trying to set label properties on edges so select a, say message flows, and set the properties I want for the label eg auto rotate, centered. left or right and 2 pos head.
Save that as a palette and apply to all message flows VoilĂ it works, sorta but I'm missing something on aut rotate at the moment.
But as soon as I relay out the palette properties are lost and I can't find where to say preserve palette properties.
