Hi, Thanks Konrad for the Sketch-n-Sketch link. I think that you hit the point about having multiple editors and views for the same object. I think that for interactive documentation that goes beyond software, that is needed, specially when you are targeting single source input and multi device/format output (like here [1]). Several Markdown variants are targeting such scenario, that includes interactive documentation, but is not their only concern. ATM seems that new GT is pretty tied to Pillar and software documentation (which is fine, but not the path I'm primarily interested). [1] https://mutabit.com/repos.fossil/mapeda/ I will see what future Pharo 7 based toolkits bring on that front. Cheers, Offray On 1/1/19 16:50, Tudor Girba via Pharo-users wrote:
