Will you be at ESUG?
I'm not sure yet, it depends more on my university than me... but hopefully I will know soon.

Ok. I still haven’t my flight ticket. But it is likely that I will attend.

It would be great to meet!

I have produced version 1.52 of Roassal. ConfigurationOfRoassal2 in the repo Roassal2 and MetaRepoPharo4.0

Thanks, but would it be possible to also include Roassal2Spec-johanfabry.6? This would probably be needed in all versions, because otherwise one cannot use Roassal2Spec in latest Pharo.

Done!

But best is to solve the Trachel issue with the callback.
I know, but I need more stable environment (I can easily deal with it, but when other people are working with it and are not necessarily devs, I need a more stable environment for them).

Yes!

I have some ideas about having more free composite shape, where I could specify (either with blocks, or having the option to subclass CompositeShape) what kind of behavior I want, but it definitely needs more refining. Because recently I ran into issue that when resizing a composite shape I wanted to resize only two of them (borders) but not another two (icon and label), so I had to abandon CompositeShape for that problem and do it manually.

Ah ah! You are facing some of the trouble I have already experienced with composed shapes. This is indeed a serious beast. Welcome on board!!!
