@ -30,11 +30,10 @@ The following is a summary of major features implemented in this version:
system.
- A optional status line (enabled by default).
- Window history and copy and paste.
- Support for VT100 line drawing characters.
And major missing features:
- Support for VT100 line drawing characters (they will appear as jklmx, etc).
This is most noticable in ncmpc and in elinks if configured with VT100 frames.
- Status line customisation, beyond presence and colour.
- Mouse support.
- No support for programs changing termios(4) settings or other tty(4) ioctls.
