I don't know if this has been suggested before, but here goes.
Suggestion: Implement the Day/night system into the next A-Map, making it compatible with the possible wild pokemon encounters (e.g. at day you see, lets say, zigzagoon, and at night you see hoothoot instead of zigzagoon)
How it works: Well, obviously, first you must have the day/night system ready on your ruby/sapphire/emerald ROM. Then, A-Map should be able to detect it, and synchronize accordingly.
I'm pretty sure this is one hell of a job, but if it's possible, please give it a shot, it would be wonderful! :D
