The Motif default theme was quite handsome, and the "demo" Motif Window Manager worked pretty well, but Motif was something of a nightmare to work with

The API sucks real bad, and even at the height of Motif popularity, the package itself was riddled with bugs because proprietary UNIX vendors never updated that shit

Motif was super-obviously designed by C++ programmers who could not ship a C++ library for technical reasons. So they tried to do a C++ API in C. And it hurts like a pineapple thrust into the wrong orifice, leafy-part-first.

Not really, because it wasn't a thing when Motif took off.
