The biggest change of this release is a new "CSS" tabsheet (see intro), that allows you to customize the CSS of the drawing:
This CSS is scoped, which means it will be applied only to the CSS of this SVG node.
However this has required a lot of changes in the code.
Therefore it would be nice if some folks could test this version, and give feedback.
Since it is not yet published to NPM, you can install it directly from my Github repo (from within your .node-red folder):
npm install bartbutenaers/node-red-contrib-ui-svg
And last but not least: thanks to @Steve-Mcl for an in-depth review of the code, and his enhancement proposals !!!!
Have fun with it,
