Complete imported type names after New and As

Code completion does not suggest a type's short name after importing its namespace. For example, after Import Einhugur.GraphicsFormats, typing Var exporter As New RawBmp does not suggest RawBmpExporter, even though the completed declaration is valid and member completion works on the resulting variable.

Imported types should be suggested by their visible short names after New and As, and wherever general completion offers type names. Using the fully qualified type name remains a workaround.
