Norganna's AddOns

I was just thinking about an add-on I'd like to see and wondering if anyone knows of one that has already implemented the idea, or if those that have already worked on add-ons believe that the idea would be too large or otherwise a bad idea. The general idea is to make an add-on similar to the gatherer add-on with the points added to the in-game maps for items but take it a step or two farther. I was thinking of linking it to the quest list and perhaps uploaded statistics for the location of npc's and drops for the completion of the quests. More or less creating a add-on that would gather statistics for the drops and locations of the items or steps to complete quests, and have a data back-end to start with some of the points. the complete dream would be to have an add-on that kept track and adjust the locations indicated on the map to reflect the current quest list for the individual using the add-on. Thus cutting down on the time spent hunting around and to some extent creating an in-game quest guide. I'm willing to help work on the add-on if it doesn't exist, and those of you with experience believe that it's do-able. I have some coding experience (b.s. in physics from cal poly) but I wouldn't consider myself a gifted programmer and I'm not familiar with the language for wow. thank you
