Suggestions about the Relationship between in-game Maps and Regions(MCA)

I stumbled upon a slight shift in regions and maps while collecting maps-that must be because birth points are still at (0,0) for some players who started with a map, this offset point was set to X= - 64, Z= + 64, which partly caused me to misjudge based on the MCA files (* especially if I don't have any software installed that I can edit MCA and view it with out minecraft mapping rooms) , perhaps it's time for the map to return to its original alignment, and for those drawing with the map, they can lock up their drawing with a glass. It's also a question that could easily affect the scope of the map upgrade-everyone thinks it's the way to show what it will be in the work block: expanding like a white sheet of paper around the map. This should be the second feedback improvement, a display issue, where the map extension should be clearly mapped out where it will be pasted so that players can determine if they need to actually consume paper to upgrade a map.

Because this is a complex topic, I thought the topic tags should be mixed, but surprisingly there was no such option. But I think the most needed improvement is to fix this tiny 64-blocks offset on map, wish the new push version will take it fixed
