Tab-caption image

I have a tab with caption “Settings” that I would like to change to a gear icon.
What is the best way to do this?

I drilled down and found that JUCE’s TabbedButtonBar class is used, which contains TabBarButton s that have a TabBarButton::setExtraComponent() function which places a component either before or after the text. Does extending PGM to support this (leaving the text blank) sound like the way to go?

That is a nice feature request, thank you. I don’t know when I am able to add that though.
