I haven't looked at this in a long time and it's unlikely I'll finish it as I stopped using Arc. Feel free to fork and update this.
Once I'm done and figure out how to package this properly you won't have to do this below.
- Place Arc-Dark folder in Packages/User
- Open Arc-Dark-Master.sublime-theme with an editor and replace all custom asset paths with your own (unless default assets are used)
- Place Widget.sublime-settings in Packages/User
- add "theme": "Arc-Dark-Master.sublime-theme" to your user prefs file.
- add "color_scheme": "Packages/User/Arc-Dark/schemes/Arc.tmTheme", to your prefs file or add through the user menu
