My fork of One Dark Pro. Customized for me. The extension can be found here or installed with ext install Egoist-One.
We also have flow support!
If you would like to play around with new colors, use the setting workbench.colorCustomizations to customize the currently selected theme.
For example, you can add this snippet in your "settings.json" file:
"workbench.colorCustomizations":{
"tab.activeBackground": "#282c34",
"activityBar.background": "#282c34",
"editorGroup.background": "#282c34",
"sideBar.background": "#282c34"
}
