Thinking about how other CAD packages work ...

Extending options for showing points :

once I™ve drawn a spline, I often highlight it™s points (by fence) to edit with the points turned OFF

I find this great as I still get the clarity of the spline

the downside is you often have to fish' for them (with a select fence)

What about an option for

Points 'ON by proximity™ (of the cursor)

That way - any available edit points would show only when you pass the mouse over their proximity

This could work perhaps 'by area™ or by object™

so mousing over a spline or a cube for example could show it™s available edit points - in grey

we could also look at an option for turning Points ON for selected™ entity - this too could be very useful

I second that especially between points of a curve. The end points I have no trouble as the cursor selects the end point of the desired curve assuming you have show points on.

I'll second that, it removes many steps.
Also, when selecting vertexes it would bs helpful to have more selection options: select along U or W ( like XY), select next with option to deselect current vertex, mirror select about the surface axis ( U/W), and the list goes on.
