Netvarec Studio has unveiled Inkvar, a font editor covering drawing, masters, spacing and kerning, proofing and sharing, developed with Displaay and NC Type. It will run on Mac, Windows and Linux; early access opens to small groups from a waitlist, and pricing has not been set. Daniel Quisek presented it on TypeDrawers to gather designers' needs.
a Linux build is a rare promise among commercial editors; the open question, raised on the forum itself, is what it does that Glyphs and FontLab do not.
