Window padding background follows background color of adjacent cell

[murtaza64]

It would be a nice-to-have aesthetic enhancement for the background of the padding around the terminal to follow the background color of adjacent cells. This would make statuslines in programs like vim look marginally better.

Not experienced with building terminals so no idea how difficult or performance-intensive this would be, but I feel like it would look nice :) It would also be cool if this could be configurable per-edge (I would personally only use it for the left and right edges)

I am bored so I will try my own hand at this before asking for the help of someone more experienced

Thanks for the suggestion.

However, I'm not interested in taking a PR to implement this enhancement because that would make it difficult to later make changes to how panes are composited and/or allowing changing the font size of individual panes.

I spent the evening implementing the feature (before reading your reply 😅), and the way I implemented it it only considers the outer window borders, not the border between panes. If you have time. I would love if you could take a look (#4175). I'll attach some screenshots there

I would love to see this implemented. I really like using strong color schemes in TUI apps to know what is open at a glance. But having the padding color never change makes it really stand out.

This is with Helix's default theme:

This is 100% a nitpick on my side, and I completely understand skipping this if it would create too much work, but I just wanted to show my support for the feature request.
