P: Photoshop 22.0: Where is Line Weight/Width and Pixels options?

Yep, @charles_uebele , 100% agree.

@ericpwl13 , to clarify, Stroke is how you adjust the width of your lines, now; the ability is not gone.

Let me know if you have a workflow that is stumping you and I'll be happy to see whether that capability is moved or removed.

Good to know. Would be better to make the parameters for the arrowhead editable in the properties panel. 

Thanks, Mark, for your empathic responses to these issues. It's refreshing.

It may be that the confusion here is that the Line thickness, while yes is controlled now by Stroke, the stroke weight option doesn't appear to do anything until you set the Stroke Options to either Center or Outside. 

You need to set the stroke options for the stroke type that you want and you need to make sure that the stroke width is > 0 . The default is that no style is set.

It's been like that for a long time (in Windows) and it drives me crazy too. 

When I rasterize, it just disappears. No lines show up.

Select the shape layer and rasterise it. Use shift + tool to draw more shapes on the same layer. For freehand pen path, convert path to smart object and rasterise it.
