I can only speak for myself. I’ve never heard of this application! I stick with FontLab, which I’ve been using for ten years. I dislike changing software and having to learn new stuff when the old is familiar and perfectly adequate; however, I have been hearing good things about Glyphs recently, and will give that a try soon.
I prefer to centre the cap accents, on the principle that accented cap letters will more often appear in the interior of words in all-cap settings, and the accents should centre in the width between adjacent letters, just as the glyph they modify does.
Shinntype’s best-sellers at MyFonts are Beaufort, Bodoni Egyptian and Brown, all of which were originally published at MyFonts at least 15 years ago, are close to the top of the alphabet menu, and have been updated to “Pro” OpenType status.
The only reason I spend so much time designing more typefaces is to amuse myself. If I were a better businessman, I would instead be extending those established B-brands with rough and stencil versions (and into OTvar), and producing much more marketing material rather than bezier-wrangling new stuff.
The number of foundries continues to increase, and with it the number of new typefaces, while the quality, sophistication and amount of marketing has burgeoned. The font business is increasingly competitive, and it’s hard to catch the market’s attention. I’m lucky I got into it early and established a bit of a presence.
