Zen looks nice and some of the UX concepts (workspaces, glance, split sidebar from vertical tabs) work well. The ‘fit & finish’ and the way changes are pushed (unilaterally? Unvalidated with endusers?) feels very much like a 1 man hobby project though.

Yes, but a bad example of one very quickly heading towards autocracy. Some characteristics like screwing up your own economy and blaming ‘the foreigners’ rings a distant bell.
