Currently, maplink and mapframe support only map markers having drop-like shape. We can put small icons, letters or numbers inside the "drop", but the shape of the marker itself can not be changed. Would it be possible to implement other shapes (squares, circles) or, ideally, allow arbitrary icons from svg-files as map markers? This will make map markers consistent with the current style used by Wikivoyage. Additionally, different shapes of map markers will improve readability in grayscale (printed maps) and for people with bad recognition of colors.
Update: we could use some help on this one (no image designers on the team) - please create an SVG image for each of the needed icons just like these two files: base and mask. The second one is for the shadow and an outline. Do not change the colors of the SVG - they are changed dynamically. Also, unless really needed, keep the same position of the images as in the examples. Please license the images under CC0. Thanks!
