this is so obvious that it must have been suggested by now, but ill stick my neck out anyway.
a tool to search for pokemon in your PC storage boxes would be extremely helpful. manually searching can be a frustrating and sometimes frantic endeavor, and a quick "find pokemon name" would completely eliminate that struggle.
the filter could even be expanded to search for natures, levels, precise ivs or iv ranges, and perhaps even allow a mix of different queries [for example: adamant;pikachu;speed31].
it sounds too good to be true
