Here's where my different figure styles are right now for this text face.
- Are the oldstyle figures too tall with the lowercase (first setting in the pic), or are they okay? (Their "x"-height is currently at small-cap height.) I had them at lowercase x-height and they were certainly too small, and too up-and-down.
- The font is presently configured so that lining figs are default. If the user sets small-caps, the lining figs turn into oldstyle figs (see second to last setting in the pic). If the user sets all-small-caps, small-cap-lining figs appear. An okay arrangement?
- Not about figures, but... Would you want a nondescending /J/ form as default in small caps?
(Note that there's no kerning here--including the kerning that will eventually space out that all-caps setting.)
