Most wanted LSP features

[janekx21]

If you only had to write with a text editor + language server. What would be features and how would you prioritise them?

Example: Inline Hints that resolve ID's to rdfs:label

I just tried this, but Protégé cannot open files which have such a string after the class ID. Also in the documentation I do not find any hint that the Manchester syntax would allow such: https://www.w3.org/TR/owl2-manchester-syntax/

This is a misunderstanding. The string at the end is an inlay hint. It's an LSP feature that inserts read-only text into your editor. In this case, the label of the class corresponds to the class IRI.
Relevant LSP features include:

• goto_declaration
• goto_definition
• goto_type_definition
• goto_implementation
• references (shows all referenced locations)
• incoming_calls
• outgoing_calls
• supertypes
• subtypes
• document_highlight (highlights text that corresponds to text under the cursor)
• document_link (all links in a document)
• document_link_resolve (how to resolve a link)
• hover (shows info from text under the cursor)
• code_lens
• folding_range
• selection_range
• document_symbol
• semantic_tokens
• inline_value
• inlay_hint
• moniker
• completion
• diagnostic
• workspace_diagnostic
• signature_help
• code_action (all kinds of quick actions)
• document_color
• color_presentation
• formatting
• on_type_formatting
• rename
• linked_editing_range (ranges that have the same content)
• symbol (project-wide symbol search)

My question is what would be LSP features that would fit the development of this ontology?
