Currently, the tool is in closed early alpha. Although we have tested it before releasing it to you, there might be bugs and the tool might break when you use it. If this happens, please report it to us so that we can fix it.
At the moment, the tool can only handle 2d images formatted in jpeg, png, bmp, tiff, or GIF. This will change as the tool develops. For example, we plan to support point cloud annotation in a relatively near future.
If you have a question that is not covered in our documentation, or want to suggest a new feature, or just want to know more about what we have planned for the future - send us an email to firstname.lastname@example.org.
