In this example...
... we can see in Exhibit A, we have a good oval head construction, made from just 4 points. The character requires a hair tuft. Construct an arc, then weld one end to the oval vector. As we can in exhibit B m'lord, the shape has gone berserk, the oval shape now badly deforming.
Try adding the tuft another way - add point to the oval and Exhibit B results.
Surely, when a point is added to an existing curve, it should inherit the vector angles? Illustrator does, other vector program I use does. Why doesn't Moho?
For me, this is one of the biggest drawbacks of constructing characters in Moho - I suspect it is why people still use illustrator for building charatcer elements.
It would be useful to have this problem fixed.

I'd be very (VERY) happy, you don't know how much, if this could be resolved 
...I always have been worried about this issue, yes... but I thought that could not have a real possible solution (I always had thought in something like this 
and I have never knew if it was a good idea or if someone would be interested in a solution... Well, now that you say the solution exists, definitely I'd want to see it in Moho!
