Sometime, when I plan a flight, I consider for some legs, multiple choices. I.e. imagine my route is from A to F.
On option is A - B - F, another is A - C - D - F. The effective choice may depend, once in flight, by weather condition, ATC clearance and more. It would be nice if, in planning mode, I could enter, in the some route, both options and, in navigation mode, through a switch, I could activate one branch or the other. Today, without this function, I prepare two routes: A - B -F and A - C - D - F. If I decide to switch to route A - C- D - F, I have to click the Skydemon menu, click on Route, then select the new route.

I think that this function could be activated, like Track radial in forthcoming 3.5 version, through an option in Planning and Navigation Options menu.
I find this solution quick and smart; if you don't want more functions you can not select them in the Option menu. In this way it's possibile to continue to improve SD letting users to define the functions they wish.
