I'm stuck and i don't understand how the editor works (it seems to be different respect to the oryx one).
i've created a folder under data/../stencilsets/extensions which contains the png, svg and a json file describing my palette (basically i added an object under stencils section extending the bpmn1.1).
Now, for what i understood, i should put somewhere in the configuration that there's a new palette. i tried to modify the file extensions.json and stencilset.json under data, but these two file are created by a compiler (don't know exactly who does what).
how can i specify the new palette? what did i miss?
