Hi Doru, Thanks for your kind words. It has been an awesome learning experience to work with Pharo/Moose/Roassal and the communities around them which have such supportive people like you. I tried to test your code, and I supposed that I needed to update Moose first, but when I tried to run the code on[1] I got a lot of warnings and finally I cancel the process but after that I get warning almost any time that I did something on a playground. May be it was because I cancelled and on-going installation without finish it. I'm have downloaded a fresh beta image, and the code run just fine but I wondering: a. if there is any smoother way to update an image to moose to its latest version. b. Do you remember my minimal examples of an update using transmitions to #nowhere ? (I have published it at [2]). I imagine that now we can have something like a live update of columns at the left editing the column at the right. I will be making some experiments as soon as I have support for BibTeX on my Moose powered notebook. I'll keep you posted.
