Reading some of the posts it would appear that one item for the wish list is the ability to tap on the magic plant to get information about it. Since tapping on the store screen takes you back to the main screen it could be a menu option to view the magical plants discovered, their names and what they do.

I would also like to have another seed box and/or another planting pots screen.

Aside from those two suggestions I think the game is great....and very addicting.
