I export my orthomosaics and open them in ArcGIS Pro so I can upload them to ArcGIS Online. The tile format in AGOL uses JPEG compression for rectangular areas, but if there's any transparency it has to be PNG. That means an edge that isn't vertical/horizontal creates a lot of PNG tiles.
Because of this, I usually use the rectangle tool to draw my boundary. But I often have to trim a corner or two from my orthomosaic. The problem is when you add a vertex, the vertex goes where your cursor is. No matter what, it won't be exactly aligned with the line, so the existing line becomes angled slightly. The pictures below show an exaggerated example.
I am requesting that the Add Vertex tool NOT add the vertex where the cursor, but instead adds it to the location along the edge that is closest to the cursor, so that the original boundaries are maintained perfectly. This is what happens in ArcMap and ArcGIS Pro when you add a vertex so it would be consistent with GIS software.
Thanks!
