How to use % (percents) as measurements units (metrics)?

Hi. I studied Interactive Media course in the college (London. UK) and our lector presented Hype. I like it but I don’t understand why is it impossible to use % (percents) as measurements units?

Hype does not yet have support for percent based metrics. Thanks for the suggestion!

You can achieve some layouts similar to percent based layouts using the Flexible Layout options: http://tumult.com/hype/documentation/3.0/#flexible-layout.
