Hi @CelticCoco, I’m fine thank you and I hope you’re well. In the past, French people I’ve met have pronounced my real name with an ‘incorrect’ vowel sound and it doesn’t bother me at all. It’s like having a new name but with the familiarity of the old one 
All I know about version 5.0.0 is that it will be released when it’s ready and it’s intended that it will be ready this year. Before then, there will be public beta releases of course.
You can try the development pre-alpha now but if you do then you should use the portable .zip package, backup your configuration files and resources folder and then restore them before going back to using the formal release version that you usually use.
You can use the spline assistant to make multi-segment complex curves and snap to them but it’s a lot of work for more than two segments and making a good join isn’t easy even for only two segments.
Here is a very simple illustration:

I’ll look forward to your next tutorial video but I doubt if you’ll ever see one made by me.
