Pokemon markings, PC box re-naming are features from the original games;
I fully support those feature to be installed in any future updates.
The pokemon tabs in the PC boxes is already quite small, adding checkboxes might clutter it.
(Also, this might be a problem for phone gamers... )
Mass deleting is not something I will like; already a number of players delete pokemons by mistake(see fourm)
and asking for them back. There is no records of pokemon we deleted, chance are, more of us will make that mistake!
Since we on the topic of PC box management, I suggest the name, lvls and typing, be removed from the tabs in the boxes.
If we cannot nickname them, no use in keeping the name on. Most of us can tell the typing from the pokemon's image, no?
I do not see levels of the pokemons, are a good way to sort or remember our pokemons in the storage.
Anyway, I am just a casual player, I might be wrong on many things, do correct me if I did!!
