GoKawiilBine hex editor adds ASCII-column shading instead of full color highlighting
The developer of the bine hex editor explored adding colorized output similar to Vim's xxd, but found that per-character coloring was too costly under the ncurses-based movwin TUI framework. Instead, bine now uses special block characters (▓ for NUL bytes, ░ for non-printable bytes) in the ASCII column to visually distinguish text from binary data without expensive per-cell rendering calls.
