Suggestions for Pokemon GO

Pokemon GO is great, don't get me wrong. But there are a few things id like to see in the game; either being needed, missing features or quality of life changes.

1. Some sort of nanab-razz combination.
They have silver pinaps and gold razz; so maybe there could
make some sort of bronze/copper nanab. nanabs are useful
for those erratic pokemon, but they aren't used since they
don't help catching itself. this will give them a use in catching
pokemon.

2. Nicknames in battles
Lots of people give quirky nicknames to pokemon, but there
really is no way to show that off other than as a buddy. Niantic
censors inappropriate names anyway, so there isn't any way to
have much of an offensive name in a gym for say.

3. A recent tab on friends list.
This may just be me, but I don't like having to scroll through to
find a specific friend again when i just sent them a gift or just
traded with them. This feature would put that friend on the
top/bottom of the list if you've traded, battled, or sent a gift to
them.

edit:
4. DMs.
a way to DM friends for battle challenges gifts. also a block
option too just in case.
