Make vector lines from selection & Trace

[Markeeee 7]

Affinity Photo and Designer are not able to make vector paths/lines from a selection or to trace a bitmap image and convert it to vector. 

This is a real pain. Can I suggest Affinity spends less time on developing new software (Publisher and iPad versions) and more time adding features to the core apps that we take for granted with Adobe Illustrator and Photoshop.

I was looking to select an object and then "trace" it (trace the selection path).  Meaning draw vector lines that follow the selection.  These lines would be on a separate layer, which can be manipulated or exported separately  Has anyone figured out how to do this?

I use Serif DrawX8 to do this and then copy/paste into Affinity.
