Now in the cloud version

Now it is even in the latest stable version released yesterday.

Citazione

Mixed numbers functionality implemented (function in the Math Region, result value option, button on the side panel, item in calculation settings);

It is a sub-option of fraction type result, so you need to check that to enable the mixed numbers result (a little cucumbersome I think, a direct double option [fraction (factorization)] / [mixed numbers] would be more straightforward).
