1.) The measurement cursor needs a minimum of two color options, Black for light colored areas (think beach sand) and yellow for dark colored areas (think shadows).
2.) The imagery display needs a toggle for Bilinear or Nearest Neighbor Raster Resampling.
3.) Need to zoom in more for the imagery display.
4.) The measurement cursor need some additional cursor types for example a cross rotated at 45° with a single pixel dot in the center and a gap of three pixels outside the center dot along the lines. ( a hollow center but with one dot in the center)
5.) When using the arrow keyes to move the cursor, add a setting for how much each key press moves the cursor such as, 1/3, 1/2, 1, 2, 4 pixels of movement per key press. Yes I want sub pixel size measurements.
6.) Provide a toggle for Dynamic Range Adjustment of the Imagery.
Comment: I find the small insert in the measurement window of very low value. It is to small and the measurement Cursor covers up to much of the image.
