I think it's easy to implement because FCS seems to return all symbol uses and `FSharpSymbolUse.IsFromDeclaration` is properly set to `true` for declaration in both fsi and fs files: 

You are right :) OK, what about this: - If we are in an FSI file, we always jump to FSI file (if available) - If we are in an...
