When settings the "Windows buttons" plugin to show icons only, items in the task bar still have the same width as when displaying the labels. It would be great if the items could use the icon width as their width so that it does not look weird when you have several windows opened.
Mmm ghehe, yes I never really looked at it again. I have to make the widget allocation part of the code suitable for group buttons, so internally it is far from completed.
Fixed in cffb369.
