- explain concept

- Done:
- Rework doc of enums (types). Skip inheritance.
- All entities below model:
- Links to parameter types don't work (e.g. enums).
- Explain "store" concept
- create_* functions on model don't show types and defaults are just shown as strings even if they are enums
- Entities in tree are ordered like in ACP. Should be sorted alphabetically
- Autocompletion does not work when creating entities (e.g. what are the arguments). Jump to definition also does not help.
- Model

Start by reviewing linked issues #662, #663, #665, and #666 alongside the existing API documentation. The work is done when the listed entity, type, parameter, default-value, link, ordering, autocomplete, and definition documentation gaps are addressed.
