@Ilya Muradyan What is the idiomatic way to make on kernel library depend on another one. For example, I want to load plotly, tables etc from my custom integration?

Depends on what you wish to achieve. Honest Gradle/Maven dependencies are always better, but if you wish to load library descriptor, do it in initialization code (execute "%use ..." there)

OK, another question, if I load a jupyter plugin as a transitive dependency, will it be loaded as well? I am checking it right now, but it is faster to ask.

Note that if the transitive maven dependency has its own integration class, it will be also loaded

Thanks.

It's undefined behavior. Some of the suitable renderers will be used

OK, I think that this problem should be marked for future study, because those conflicts will appear appear rather sooner than later. In VisionForge I solve it by adding a numeric rating to renderers. So the default one is 10, but one could create a renderer of higher priority.
