Pavel I do not think that cassowary is good for us.

Do you mean Cassowary in particular, or constraint based UI in general?

My naive first impression is, if Cassowary is��good enough for Apple...

https://www.quora.com/Should-I-use-Auto-Layout

and Google (search here for "solver")...

such that "in 2016, both iOS and Android have first-party layout systems based on Cassowary."

For balance, some points against AutoLayout, but some alternatives also seem to use Cassowary solver...
