How to identify the tabs for displayed code in split-screen views?

Question

In vscode, I can identify the tab that is active and recolor the top of its tab as described in Is there a way of making the Active Tab Border highlighted on top instead of at the bottom?

But if I have a split screen, there will be a non-active tab for which code is showing in the split. How do I identify and color that tab?

Basically, in split-screen mode, the recipe above was not enough to make it clear which tab's code is showing in each group of tabs.

Answer 1

Look at the various tab.unfocusedActive.... colorCustomizations, like

"workbench.colorCustomizations": {

   "tab.unfocusedActiveBorderTop": "#ff0000",

}

which will give the "active" editor in an unfocused split group a red border top.
