Problem

While formatting figures, along with aligning axis labels, aligning titles is often necessary. To do that, without the availability of a simple and convenient method like fig.align_labels, I find myself going through multiple rounds of

Plotting → changing y parameter of ax.set_title → replotting.

Plus the re-alignments are necessary if the figure/subplot size and layout are changed.

Could there be a simple and convenient way to align the titles of subplots, using maybe a method that is similar to fig.align_labels?

Proposed solution

Perhaps the general method of how labels are aligned using fig.align_labels could be extended to align titles. I am no expert on matplotlib's API, but I wonder if cbook.Grouper could do this.

FYI, I know there is a way to align titles using subfigures and suptitles. But I would prefer not to convert subplots to subfigures only to align titles.
