Tags: patch When editing multiple buffers the `tab-line-tab-modified` face (which indicates that a buffer has been modified and not saved) is sometimes barely visible or hard to distinguish from the tab line. This patch changes the appearance of the close button icon when the buffer has been modified, similar to other editors. The patch is not yet finished, this feature is currently "hardcoded" (the only way to disable this is removing `tab-line-tab-face-modified` from `tab-line-tab-face-functions`). I would like any suggestion, if should this have an option for disable this.
