As you can see below, there is this annoying white line under the filename. How would I change its color to black? I am using the Atom One Dark Pro theme.

I believe it shouldn't be too complicated, as VS Code is pretty customizable.

1. Open Command Palette and find "Preferences: Open User Settings (JSON)"
2. It'll open settings.json. In the file, add the following entry:

   "workbench.colorCustomizations": {
     "[One Dark Pro]": {
       "tab.activeBorder": "#292c33"  // <-- Change color here
     }
   }
