Brush stroke -> extend wont work

[jonasbonas]

If i draw a stroke, i can extend the stroke. 

If i use a Brush as stroke, it is not possible anymore to extend it.  Is it a bug or am I doing something wrong?

Neither.

"Vector" brushes are actually pixel patterns attached to a plain vector curve. That only means you can change shapes or the brush patterns later, unlike with Pixel brushes. But since Affinity doesn't have a built-in image tracer *) you can't expand them out of the box.

The only true vector brush is the topmost one in the Pens category: "Solid Pen with Pressure", and correspondingly also the Pencil tool with Controller enabled, as used with tablet pen pressure or with mouse pointer/trackpad velocity. Those can be converted to outlines.

*) As it turned out just recently, there is a very rudimentary image tracer in Publisher, so as a workaround it is somewhat possible to convert at least some of those "vector/pixel" brushes to vector shapes:

That all said, strictly speaking there is a "bug" in that the "Expand Stroke" menu command should be grayed out, unless "Solid Pen with Pressure" is selected.
