When you export a view as an image file, it's always a 2048 x 1536 image. Currently you can use ray-tracing for 16:9 images up to 4K, but it's a waste of time if you don't have transparent elements and you still can't export hi-res False Color images.

It would be great if we could select other resolutions or proportions for the "regular" view export, or at least use the current window proportion.

A practical example: I have an ultrawide monitor, which allows me to visualize the model like this:

But if I want to use this wide view at my presentation, I need to manually take a screenshot. If I use the "Save image" button, this is what I get:

Which is not even 16:9.
