    Thank you for your help!
    Affinity, if you're reading this, I'd prefer to have an easy way to smooth and clean the edges of a pixelated enlarging over the ability to convert selections to paths. I mainly need the paths for resizing but prefer to adjust things by drawing.

    There’s a ‘Scale’ option in the Stroke panel to control whether or not the stroke width changes when you resize the object.
    How can you expand a stroke that isn’t there? The ‘Expand Stroke’ command creates (or tries to create!) a closed shape which mimics the selected stroke: if you start with a vertical straight line which is 50 px long and 20 px wide, you should end up with a rectangle which is 50 px high by 20 px wide.

    Hi, jtlapp,
    AD's vector shapes can have 2 attributes, fill and stroke. (If I've got this right) The built in shapes default to a pale grey fill, and no stroke. The pen and pencil default to a very thin stroke, no fill. 
    You just replied. Its not a bug that it doesn't expand stroke when there is no stroke. There is nothing to expand.
    What happens w. expand stroke is that the stroke, which is "painted" onto the vector, is turned to a vector by adding connected nodes to the boundary of the painted stroke. So a rectangle, for instance, w. no fill, but a thick stroke, 36 pt perhaps, will be expanded to a 1/2" perimeter. That new object has the fill color of the stroke, but no stroke of its own. One can then add a stroke to the expanded stroke, and expand again, creating a series of perimeter shapes.
    Because the strokes can have pressure profiles, on can make pen or pencil curves w. variable thickness. Upon expanding, one gets something like a dynamic ink stroke. 
    The routine as it stands can produce immense numbers of nodes if the stroke is highly inflected, very curved w. many width variations. This can make subsequent work doing geometric operations between various curve objects rather messy. Sometimes boolean operations will produce hundreds of objects that are invisible because they are so small, but are comprised of nodes a .001 apart.

    jtlapp reacted to R C-R in How do I preview adjustments without having to undo them?   
    Because my projects usually have lots of layers, I undocked the Layers Studio panel, moved it off to the right of the workspace window so it would not obscure anything, & resized it to the full available height of my monitor.
    One of the cooler features of the Studio panels is you can double-click on a panel name & it will hide everything except the panel name header. Single clicking on the name expands it back to its former size.

    Would be better if you could toggle on/off directly in adjustment panel. You can though toggle opacity between 0 and 100 with keyboard: double press 0 (opacity 0) and single press 0 (opacity 100).

    You can undock the layers panel and toggle the relevant one(s) while keeping the adjustments panel visible.

    Yeah. I'm now thinking this is even better than PS! I can selectively undo prior adjustments! Woo!
    Thank you both for your help!

    Apply a Curves adjustment layer. Select Alpha from the menu  then you can play around with the curve to do pretty much what you want with those elusive semis

    Ah! Then it's my misunderstanding. Thanks for explaining. And thank you for the quick fix!

    Absolutely. It provides complete control over dot size, minimal dot spacing, and threshold for completing the fill.

    Update: I've been struggling enough with halftones that I decided to write my own program for creating them. Only I'm generating random dots at relatively even spacing, instead of regularly spaced dots. What's better, random dot shading doesn't produce Moire patterns on resize. Here are examples of resizing halftones vs resizing my random-dot fills.
