Until 2.2 I think the number components were added next to each other when there were multiple in a glyph, just like letter components do. Now they are laid on top without changing the metrics. What was the reason for the change? Can it go back to the previous behaviour?
Please correct me if I am making conflicting request.
What kind of numbers do you mean. You might need to activate the alignment from the context menu. The biggest change from 2.2 to 2.3 is that (mostly) only letters are aligned by default but now there is an option activate it for all other glyphs, too.
