Works very well! I’d like to suggest that you add the inline version:

It seems rather easy, I’ve tried to compile without luck - we’re using IntelliJ. Perhaps it would be easier for you to include.
Thanks!
Not sure how that would work in a Vaadin app, but we’ll consider including code changes that have been tested to work in Vaadin.
