How do I cange the color of tab marks in selected text?
.
Sublime is using built-in Adaptive.sublime-theme with Sublime’s Legacy SpaceCadet.tm-Theme. A few tweaks to SpaceCadet.tmTheme and Settings, but no idea how I poisoned selected tab appearance. I like the tabs to show inside of selectionBorder. How to make selected tab marks a more gentle, dark pastel?
