@ -8,9 +8,7 @@ Vague musings:
- Allow indentation of marked text by spaces as well as tabs?
- Allow indentation to add just enough columns to reach the nearest
multiple of tabsize, rather than always adding tabsize columns?
- Allow conversion between different character sets. Maybe use glib's
iconv() if the system's iconv() is inadequate, since we already use
glib's vsnprintf() if the system lacks vsnprintf()?
- Allow conversion between different character sets.
- Allow setting marks (saved positions, not to be confused with the mark
set via Ctrl-^) at various lines and/or columns in the buffer, and
allow movement between them with a single keystroke?
