Introduce put_line().

Browse source 
This function is a fully-fletched, high-level pixel-based line printer, that
combines functionality of several firmware and list functions. It can
draw spacing, icons and text in a single call, in any order and each multiple
times. It can also apply line decorations at the same time.

It features printf-like semantics by accepting a format string that contain
format tags as well as inline text.

It's accessible directly, but also through the multi-screen api for plugins.
