Hi Gabor, finally found some time to work on this. Should be done in the
next day or so and will post a video here first for review and comments
before making it public (committing).
I'd like for you to send me some text about yourself that I can put on
the blog when writing about this new feature - just anything you would
want readers to know about you. If you could send me that this week I'd
really appreciate it.
