I think there should be a separate section in the GTS for shiny
pokemon. It would be a lot easier to search for shinies in this
way, similar to the shiny section in the auction house. Sometimes
searching for a specific shiny in the GTS can be extremely hard as
we have to skip several other trades to look for one.
So, a separate section for shinies in the GTS would be quite
helpful.
Or simply, for the shiny version of a pokemon, there should be
written 'shiny' beside their name to specify them from the normal
version of their kind in the GTS search bar, [for example:
Bulbasaur (shiny)]. I've seen this feature for the retros and
megas, therefore it also could be done for the shinies. In this
case, the GTS search bar would look something like the following
picture.
If you disagree about implementing this suggestion, you can state
down the reasons. If you have any new or better idea for improving
this suggestion, you can also state it down.
