Protractor - speed calculator, distance ruler, manual ship marker, save multiple plot points

[Destraex]

Any chance of getting some sort of scale or distance measure on a ruler as well as a speed calculator to use with the protractor?

Also the ablity to plot more than one leg of a journey and add or delete plots at will?

Also a marker so that we can put a ship icon on the map where we think we are now?

Degrees on protractor?
