The letters in the second and third line don’t look beautiful because the horizontal and vertical strokes don’t match. As I said, I'm working on a typeface design. When one tries to optically match an upright and a slanted (italic) font, several factors that influence the apparent (optical) size of the letters have to be considered: the letters of a slanted font with the same vertical x-height as an upright font are bigger along their slant axis, but their counters (inner letter space) are smaller due to the slant. Additionally, the different letter forms play an important role. Very small differences mathematically in slant and letter-width can make a big difference optically. To try out different values, I mathematically stretch and slant the letters by small amounts. Afterwards, of course, when the right values have been found, the letters have to be reworked by hand. Another use-case for the extend feature could be to stretch/compress a line (e.g. a title) to the desired length. If the line is only a little bit too long or too short, compressing or stretching all the letters by for example less than 1% can be enough to add up to the desired amount.

Thanks. It's a bit inconvenient, because for each feature you want to

that the problem isn’t related to the \definefontfamily command.

Dear list,
the (fake) extend and slant features seem to be missing with Selectfont.
Will they be made available sometimes in the future? Or am I simply
doing something wrong? With simplefonts, they work.

1. The problem is unrelated to the \definefontfamily command.
\definefontfeature [default] [default] [onum=yes]
\definefontfeature [testfeature] [onum=no,extend=2,slant=0.25]
\setupbodyfont [modern, 50pt]

2. When you apply your “testfeature” to a certain font alternative (e.g.
italic) it will work.
