[Export preview scale/size - where?]

Achieving 100% when scrolling is like trying to win the lottery. Additionally, once you change the dimensions, you cannot adjust the zoom level to preview the image quality (screenshot attached).

I am confused as to why such a fundamental feature is missing from the program.

Is it really that difficult to code the ability to "Export image with preview panes" in under 10 years? I'm not trying to be clever, I'm just being REAL here.

What am I missing?

[Quality/image preview when Exporting]

I'm very interested in using Affinity Designer, but I'm confused by the Export Image function. It seems odd that a program as intuitive and easy-to-use as Affinity Designer would lack a fundamental feature like a robust image export and preview function.

Can someone please help me understand what I'm missing here???

[Export preview scale/size - where?]

Totally Confused: How can I preview image quality?

This is a fundamental feature that really should work out of the box. When I click "Export," the image previews settings should be readily available (see screenshot).

I'm stumped. Please educate me.
