Identifying the running icon from several in tray?

Thanks, interesting. Not easy to compare as I have a tool called '7+ Taskbar Tweaker' installed. I also have a very full taskbar and tray, so in...
Settings > Personalisation > Taskbar > Combine taskbar buttons

  • Always hide labels
  • When the taskbar is full
  • Never

...I currently have Never selected. How did you configure to get your labeled result?

I can see full sketch names by (patient) hovering, but was hoping there might be a way for the IDE (which must know the name of the executing sketch) to reflect that somehow.
