As posted in the previous weekly meeting notes, I’d like to discuss roadmap / architecture and design for the components that should be refactored in pure VTK C++ so that they can be reused in SlicerWeb / trame-slicer usage.

- CMake - vtkmodules update (NEW)
- Main slicer application (initialization / connection of the core modules)
- Views (decoupling from CTK / Qt to pure VTK)
- I/O Manager + plugin mechanism
- Subject hierarchy + plugin mechanism
- Segmentation editor + plugin mechanism
