We would like to have a compact StatmentView.
Therefore we should consider relocating the Add Statement Toolbar.
And we also may want to replace '0 references' with 'add reference'.
More compact view features:
- collapse groups of statements (e.g. all external identifiers)
- ignore groups of statements (e.g. all awards and nominations)
- summarize groups of statents (10 external identifiers instead of a detailed view of identifiers )
