Build a feature that allows to annotate lists based on Wikidata.
Basic use cases:
- items locally selected from query. selected new ones by default (or not)
- items added/selected manually (current Wikivoyage approach)
Annotations should be stored locally. Samples for annotations:
- commented featured list at enwiki
- Wikivoyage commented listings
- episode lists with summaries per episode (on various wikis, notably enwiki).
