It’s left-aligned. How can I get it centre-aligned again?
There’s a new button to set colors to black and white. I don’t want it, I guarantee I’ll click it by accident and lose my colors. Can I get rid of it somehow?
Hm, I cannot help as I have no idea, but it would be interesting to understand which gimp version you are coming from, as in my gimp 2.10.30 both the left alignment and the black/white button are already there.
Hmm. GIMP 2.10 used something called GtkWrapBox for that part of the toolbox. Looks like it was removed in GTK3 and so we replaced the widget with GtkFlowBox. It appears to work differently - even if the other children aren’t visible, they still take up space. We might be able to switch to a different widget to recreate the old behavior.
