Though I cannot help, I will +1 this.
I am unable to stop any scanning until I have selected at least three points on the map. This is an issue when I make a mistake or I need to verify my settings because the scan must be abandoned completely and restarted from scratch – unless there is something that I am missing.
If am not overlooking something here, the appropriate behavior should be that the operator can abort the survey at any time and return to the settings of that specific scan without having to start from the beginning. I would like to be able to back out to the settings so that I may verify or change settings and then perform the survey.
