I would love a stamp asset that depicts latitude and longitude lines of different kinds of map projections. The asset would include different variations of a grid that can be placed on the top layer of a world map. I attached three examples of what I mean.

Currently, the best option we have is the grid tool, but that is limiting since it can only make equidistant lines. Or, I have used the line/shape tool to create a custom grid, but it's very time consuming and is difficult to create a perfect grid. Originally I was going to request this as a feature, perhaps an update to the grid tool. But I think it would be a lot simpler (and just as useful) as a pre-determined stamp asset.
