Not a minimap, just a map that looks kinda like a minimap, but is only accessible when not in game (Like texture packs. Without optifine, you can only open that from the main menu.)
When I said minimap, I just meant that it would look kinda like one, even though it doesn't function as one whatsoever. (since you can't access it in game, you cannot refer to it in game. I don't see why this would be a problem since you can download the maps anyway.)
A side note as well: Like I said, no need to rush these kinds of things, either. If you are still new to this stuff, that might be a bit much to tackle. Work on a few smaller things first (like the server number and stuff), it'll be better that way in the end. Start small, and slowly work your way up.
