Research direction

No files, tests, or entry points are named in the issue. Start by examining the existing arc and line layers, then determine the scope of arrow support described here; done should include target arrows with selectable shapes and adjustable size, plus the proposed origin-latitude, origin-longitude, and azimuth inputs if a separate layer is implemented.
