@adripo hi and thank you for you contribution. The changes are OK, but because of other recent PRs, there are now conflicts with the master branch and PR cannot be merged. Since you didn't allow modifications, I cannot do it myself. Please, try to sort it out, or change the settings of this PR that will allow me to make changes directly.

Hi @AloisSeckar , thanks for the checks. I enabled edits on the PR. I don't have much time to work on this in the weekend, maybe next week if you still haven't solved it yet.

Since it was pretty quick resolution, I have done it :) Thank you for help with the actual demo.
