An option to the file order such that directories are mixed with other
files (probably -m).
A mechanism to allow 'default settings' for NDir that apply on every invocation. An important application for this would be disabling display colourization if needed.
The support for coloured output works, but is probably not portable enough for some systems.
In a future version, NDir may allow combined options (e.g. -la instead of -l -a). In that case, options -ca and -cn will have to be renamed.
