Journal Entries for PE

I thought up a new idea that could be useful to some people. A journal for Pokemon Essentials. I know it sounds like Diamond and Pearl but it's somewhat different. What I came up with is a journal that records any important meeting's with important people. Such as you meet up with the prof. and get your first pokemon or you battle against the champion for the last time. Some people should know what exactly I mean. I wonder how this can be made possible and if I can get a scripter to help me make it possible. It's a good idea I think but it could be used for much more. Maybe a digital recorder that record's any movement that you have done but with the idea's from before. Some what like Fire Red and Leaf green. But displaying the most important thing's in the game. Such as you use a switch to show it must be recorded. If anyone can tell me that it's useful and you can script something like that please tell me. I want to use this idea I think the most out of all my idea's so far.
