Hi Smiljana, In the ideas/inspiration front maybe you could check my outliner prototype for data activism, visualization and storytelling, called Grafoscopio[1]
[1] https://mutabit.com/grafoscopio/index.en.html The notebook interface models a document as a tree. It was my first program made on Pharo to learn it (and also to make research based design for my PhD), so there is newbie code still there. I'm slowly remaking it, but was really helpful to have an environment that didn't punish me for my learning process and allowed me to refactor the prototype as my understanding of the problem, prototype and coding environment as improving. In any case, I remember needing tree objects implemented in Pharo, but I didn't find anything, so I implemented them by my own. Install it and check the manual (is a little bit outdated, but it should work). Hopefully Grafoscopio can be insightful for your project and also I'm interested in feedback about it (and with more time to address it, after finally finishing the PhD and just waiting for the long bureaucratic graduation process and paperwork to finish).
