I was animating a long 'brush line' curve with a very irregular stroke width through another curve using Follow Path, and because there were so many points along the 'brush line' art curve, I was wishing there was a way to adjust the line thickness with a fall-off brush.
That's when I happen to see the Magnet Mode option in the Line Width Tool options. So I clicked it on and, whaddya know, Line Width now did exactly what I needed.
To use it, enable the Magnet Mode option, then hover the cursor over the region you want to make thicker or thinner. A red circle will appear just like one for the regular Magnet tool. Next, click drag the mouse L/R and the stroke will get thinner/thicker inside the circle region with a fall-off effect at the edge of the circle. Just like with the regular Magnet, you can change the circle size by using Alt+LMB and dragging.
I'm sure this option must have been in Moho forever (I see it in 12.5 too,) but since it completely slipped past my radar, I wanted to point it out for others who may have missed it. Line Width Magnet Mode is probably going to save me a few hours of work today and save my mousing hand from extra fatigue.
