the new version (2.5) ordered the basic letters in a better way. There is now a linebreak after the uppercase letters, after the lowercase letters and also for the greek glyphs.
I wold like to have this feature also for the figures. With oldstyle, lining, tabular, sups, dnoms, etc it is really getting hard to open the same figures to compare them quickly. It would be cool to have a line break after each set of figures, that all zeros, ones, etc. are in one column.
that it’s what it look like now
a quick and dirty sketch
