Feature request: export sizing

[Markus Allen]

I would love to see a future Affinity Designer that would remember the canvas size when exporting (a .png for example).

Sometimes, the export size is twice... sometimes 400% bigger than my canvas size. (It is weird - there is no pattern to this).

Right now, I have to back out of the export to see what my canvas size is... then hit the export option and manually input the width.

Even better:

Let me select an object, and when I export it as a .png (or similar format), Affinity would automatically size is right (instead of setting the export size to the entire canvas size).
