Hi Heiner, in the future I do want to make a way to edit the "through points" later on probably by some extensions to the history function.

For now though it can be best to delete the current curve and redraw a new "through points" curve through your new location.

Hi Michael,
good to know that it is on your list already!
For the time beeing I work with a technique similar to what you suggested.
Its working well but as you can imagine its quite time consuming when you
have to redraw instead of just doing your corrections.

I agree this would be very useful feature to have in Moi.

In ViaCAD I use these interpolated curves nearly all the time and having the tangency handles at each end of the line is incredibly useful.
