Comment (by nomeata):

 > My thought would be to display everything unqualified,

 Let’s get more concrete. Assume we have this module:
 {{{#!hs
 module Foo
 import Prelude hiding (Either)
 import qualified Prelude
 import Bar (OtherType)
 type SomeType = ..
 type Either a b = ..
 foo :: SomeType -> OtherType -> Either a b -> Maybe a -> Prelude.Either a
 b
 }}}

 then currently `:browse Foo` (with only `Prelude` imported, but not `Bar`
 or `Foo`) would give this

 {{{#!hs
 > :browse Foo
 Foo.foo :: SomeType -> Bar.OtherType -> Foo.Either a b -> Maybe a ->
 Either a b
 }}}

 Your suggestion (everything unqualified) would be

 {{{#!hs
 > :browse Foo
 type SomeType
 type Either a b
 foo :: SomeType -> OtherType -> Either a b -> Maybe a -> Either a b
 }}}

 while mine would yield:

 {{{#!hs
 > :browse Foo
 type SomeType
 type Either a b
 foo :: SomeType -> Bar.OtherType -> Foo.Either a b -> Maybe a -> Either a
 b
 }}}

 Note how my variant of your proposal
  * avoids disambiguities in the types of symbols, if there are name
 clashes with type in scope
  * still indicates modules of symbols that are neither in scope nor from
 the browsed module
  * still avoids lots of module prefixes
