What picker do you refer to?

all builtin lsp symbol pickers, lsp_document_symbols, lsp_workspace_symbols and lsp_dynamic_workspace_symbols.

It would be useful if you would give a screenshot of the thing you are talking about from ionide-vim.

The textDocument/documentSymbol request has a return type of something that inherits from lsp.BaseSymbolInformation which has the fields:

---Provider options for a {@link DocumentHighlightRequest}.
---@class lsp.DocumentHighlightOptions

---A base for all symbol information.
---@class lsp.BaseSymbolInformation
---The name of this symbol.
---@field name string
---The kind of this symbol.
---@field kind lsp.SymbolKind
---Tags for this symbol.
---
---@since 3.16.0
---@field tags? lsp.SymbolTag[]
---The name of the symbol containing this symbol. This information is for
---user interface purposes (e.g. to render a qualifier in the user interface
---if necessary). It can't be used to re-infer a hierarchy for the document
---symbols.
---@field containerName? string

---Provider options for a {@link DocumentSymbolRequest}.
---@class lsp.DocumentSymbolOptions
---A human-readable string that is shown when multiple outlines trees
---are shown for the same document.
---
---@since 3.16.0
---@field label? string

So the container name could be used for what you need but you need to tell me how it is shown in ionide-vim to know how to format them.

The requests in Ionide-vim seem to be fsharp specific. For example rather making a textDocument/documentSymbol request it does a fsharp/documentationSymbol request. Though I know almost nothing about LSP

Those those pickers use a single function to make the display. That function is make_entry.gen_from_lsp_symbols. So this should be very doable.

Is the previewer not adequate for seeing context?

@jamestrew not unless you have found a way to display the "fully qualified path" inside the previewer? I mean, thinking about that it would be awesome to able to use nvim-navic in the previewer or an extended column...

For reference, vscode displays the containing symbol

I think a Telescope results list like the following would be extremely cool:
