A bit weird to not mention that.
Unfortunately until editors start supporting this (and I’m not sure what would motivate them to), these remain great ideas only.
I more meant the idea of using different fonts in the same buffer to represent different kinds of text.
Monaspace is a monospace font that uses contextual alternatives: it changes how letters look depending on surrounding letters.
They are nothing alike in their approach to this problem.
(Also this is a marketing piece. Contextual alternatives is not a new tech.)
it is also a monospaced font
Mixing monosoace and proportional fonts can be a little strange, but there are some 3rd party packages or guides (prot has one iirc) to workaround it.
