Ilario V. asked me (Valerio) to explore this lovely tool called "What to do" and currently hosted in Wikimedia Toolforge - with source code published in Wikimedia GitLab:
https://whattodo.toolforge.org/
https://gitlab.wikimedia.org/toolforge-repos/whattodo
The goal is to understand how the tool could be expanded for the purposes of Wikimedia CH, eventually helping current maintainers / developers with support.
