Terminal Background Image

What feature you'd like to see or proposal(期望什么新功能/特性或者建议)

Hi, I’d like to set a different terminal background color for each bookmark, so I added a background image in the bookmark settings. In the old version, I used a large image to cover the entire window. However, in the new version, the image is centered and no longer fills the window. Could we add an option to align the image differently or select a background color instead of using an image?
