"... something that was a kind of quick trim of everything past the end of the curve"

I agree. I think a single click to auto-trim over hanging segments from intersected lines (and join the result) would allow for very fast drawing.

Much like quick hand sketching where you are concentrating on the overall shape (and not clean end points) and go back and erase the over-hanging lines.

I know you can use the current Trim function, but not in a single click as far as I know.

Would be a neat feature especially when used with fillet to round the intersections afterward.

Good for tablet drawing as well.
