IntelliJ IDEA: 2016.2 font ligatures
The new version IntelliJ IDEA 2016.2 is out!
It includes a new feature to support font ligatures.
It looks very promising, so I downloaded and installed the font FiraCode.
But I noticed rough edges in the font.
I enabled the feature in Settings → Editor → Colors & Fonts → Font
and selected FiraCode
as Font.
