[NTG-context] spacing of values and units & ^{-2}

Hi, concerning m-units, it would be nice to configure whether to use a full space or a thinspace between a number and its unit. Furthermore, some space is needed between adjectant units like in 1\Meter\Inverse\Second. I know there are some old threads concerning this topic, initiated by me. But have there been any recent changes to the module, or are such changes planned? Btw: How to get a power to the minus 2? Neither 1\Meter\Square\Inverse\Second nor 1\Meter\Inverse\Square\Second work. Greetings, -- Eckhart
