We've added a new way to create Custom Annotation Markers: You can now select from an existing set of icons instead of uploading your own graphic assets. No more need to always upload images for new markers - simply pick an icon, set the colors, and you're ready to go.
Of course, you can always use your own assets too! But if you don't, this is a quick and easy way to get started. If you don't find an icon or symbol you need, let us know and we can look to add it.
