Could you provide a highlight group for buffer names in the status line corresponding an active and modified buffer? Similarly, I would like a highlight group for buffer names that are inactive while the active buffer is modified.
The reason is that at the moment vim-bufferline is clashing with airline. For example, If I modify a buffer, all buffer names in the status line get colored with red except the one that was actually modified:

What I would like is to color the active and modified buffer with red (bootstrap in this example), and color the rest with their default highlight.
