I noticed that in the last Cabbage releases, the titlebar (and the contour of the window) of the running Cabbage plugin is grey, instead of the previous black.
I think the synth/fx developer should have an option to change the window/titlebar color of the Cabbage plugin. For example, in my case, for the graphics of my experimental synth interface, black was more suited.
So, I searched in the Cabbage source code and I found where you can change this:
For example, if you change the line 48 with this:
48| Colour(0, 0, 0),/*LookAndFeel::getDefaultLookAndFeel().findColour (ResizableWindow::backgroundColourId),*/
you'll get back the black titlebar color.
Of course, it would be very nice if we could set this color with a 'titlebarcolor(...)' identifier of the form widget (and I noticed that identifier already exists in the source code but actually it's not used).
I tried to make it work but I could not do it because I have no access to a ValueTree widgetData inside that function...
