I Would Suggest A New Feature that you can customise in the settings if you make a custom profile that you can use a picture as Icon so that In the Taskbar It Lookes different. This feature Will be getting well with when you will Add Multiple Intances But would be cool also right now. Like The custom icons in the vanilla launcher where you can use different blocks as icons or like in Prism Launcher.
I think i Explained this very troughly Thank you for your time.
