+xThank you Marc very much for your enhanced explanation. I look forward to hearing comments from others.
My first instinct is that this would be a retrograde step. It's adding a feature which only benefits somebody who is using stopwatch and compass style navigation, whereas if somebody is using SkyDemon they have already made the decision to move forward with GPS style navigation. That combined with the fact there is unlikely to be a consensus on the frequency of the ticks (or even whether they should be distance or time markers) makes me think it will over-complicate the product when most people are very happy with the way it works.
As always I reserve the right to change my mind if it becomes clear that lots of people want this.
i agree with marc is there an update coming soon for placing timeticks in the future on SD
