I have Progrids Asset running but when editing and adding curve points it ignores any snap settings.
In a previous version I could change the scripts to add this behavior but I wonder of there is a new or improved way. The previous way would get overwritten by updates.
If not I think this could possibly be a fairly simple addition where you could add a snap setting parameter to the curve UI.

Thanks

I added this as an RFE. Currently, there isn't a new or improved snap setting feature. Will remember to update this thread when it has been added.
