Upgrade to the latest daily build (1.49h9) and the point tool will record slice positions if you enable "Add to overlay" in the Edit>Options>Point Tool dialog. The "Add to ROI Manager" option in the same dialog also records slice positions. Note that these options only work with the single point tool.

It seems like an odd request but a none Selection color plus a large Marker size with the Cross color set - would highlight the pixels in the image where the point was marked- you would see 4 segments of a cross with and an unmarked centre - could see what was chosen.
A "none" option for the selection color would not work because it would simply uncover the complete crosshair. The latest daily build, however, has a "Type" drop down menu in the point tool options dialog that allows you to select a bare crosshair, a dot or a circle.

The length property is a language feature, not a function. Add ".length" to any array variable to get the length of the array. Java and JavaScript also have array length properties.
