+1 vote for doing non-uniform scale.
Let me describe the purpose. I use it for making tiled texture tiling not so noticeable. For example if I have 1 wood plank texture and I create 100 plank faces and apply texture to them - this is Not very convincing. I can add some variation by using Random Select + Scale and Rotate Multiple to rotate some of the planks 180 degrees around their center points. Now tiling is less noticeable. But with Random Select + (-1 Scale X/Scale Y/Scale XY) I can have 8 different variations from a single texture! basic+3 scale variations + 180 rotated+3 its scale variations

I've just noticed that ClothWorks doesn't work inside Groups: you just can't see it's context menu.
I.e. if you have empty scene with your cloth geometry inside the group and this group is on top level inside the Outliner, then you can right-click, make it Cloth (or collider) and so on, like it is shown in all those Youtube videos.

But as soon as you put your "Cloth" group inside another group or component, get in this grouping group, you can no longer see context menu.

This is very restrictive, most scenes are very complex and have complex hierarchies.
