The vertex snapping for the tube is fantastic.
Please extend to other tools:
It would be extremely practical with the Transform Tool or for the Pivot. Even with the lathe tool you might need vertex snapping.
And of course vertex snapping for other vertices with the move tool.
This is such an upgrade!.
Stephane said UI will be updated …
for now change setting in the 3 dots submenu.
He also needs to add it to the curve array
The curve repeater now also has vertex snapping - great.
I’m greedy - I hope for more… 
I just used the tube today (since I can’t remember the last time). Took me a moment to figure out why snap wasn’t working like usual. Then I remembered reading about this whole vertex snapping thing. Had to find where to turn it off. And then had to turn it off again when I made the next tube.
While I’m glad it has its uses, I don’t know that it needs to be on by default.
Yes, please turn it off by default 
I almost had an orgasm when I realized you can snap to grid !!!
