[I don't know if this is the right place to post it, but I think
there should be a notification that you receive when a Pokemon
starts eating your honey. It is really annoying to know that
usually there is no Pokemon around, and when there is, it has eaten
your honey.
if you go to settings and then hit miscellaneous settings you can
set the alarm clock from the mall to give you hourly notifications
to check the honey tree, usually if you check once an hour youll be
safe, and also if you check too often theres less of a chance of a
pokemon showing up, so checking every 5 minutes or even every 30
minutes isnt a good idea.
In the mall, you can buy an Alarm Clock to set a notifier to send a
notification in a certain amount of time. It notifies you about
both the Honey Tree and Wonder Trade Station, so you should buy
them, as this suggestion would be classified as "This would
simplify an existing feature in an unnecessary way".
The same idea was also rejected. There is probably more threads that was
rejected or in the wrong forums.
