Lunacy for Linux and Mac OS is VERY VERY CLOSE!!!
NO strength to endure?
Variable Fonts Support
A variable font (VF) is a font file that is able to store a continuous range of design variants. An entire typeface (font family) can be stored in such a file, with an infinite number of fonts available to be sampled. But I found that Lunacy does not support variable fonts.
Sometimes when I choose a variable font, Lunacy only display the thinnest weight although I choose other weights. So hope Lunacy can support variable fonts. This is a important feature for a design software.
