Background image customisation, Themes area not ok

Hi,
This is more of a *creature comfort* than anything. Coming from Windows Terminal to this has been a breeze but one thing I'm longing is the actual image setting rather than just importing an image and off we go.
So what I wonder if this could be achieved as per the screenshots I've provided from Windows Terminal.
**Settings list:**

**Image stretch mode_**

**Image location:**

This is also an inconvenience in the Themes section. The image covers the whole background area which makes it hard to see any other color scheme/theme. So perhaps a dark mode or make the image smaller after importing? It could be a smaller image under the selection color when previewing the theme. Now it just is there and hinders the user experience very much.

The current image alignment when using Windows Terminal names is "uniform to fill" and in the center.

The image used is a png with transparent background sizes 800px by 800px. Resizing the image does not work.
As this screenshot indicates:
That bg image is 200px by 200px.
