Hi Doug,
Sorry for the inconvenience caused.
In v.5 you can move the link's end points to resize the link. We have not implemented the add/remove bending points(Vertex Edit functionality) in v.5.1 beta. Currently our developers are working to implement this feature. The fix of Vertex Editing (Adding and removing the bending points) is available around June 15.
Vertex moving functionality for all links is available in v.5. Please refer to the attached video file.
Video.zip We do not have a firm date for the release yet. There will be a beta refresh this week. We have had some issues reported during beta testing and the final release will depend on resolution of these. I will let you know the release date of our main release at the earliest.
Thanks for your patience.
Regards,
Nagaraj.
