I did a brief evaluation of it a few months ago as a possibility - we’re also evaluating it in some projects at my day job. 

The APi is interesting if you’re starting from scratch and only exclusively in C++, but it’s not a great fit for how we define GUIs in FG (via XML/Nasal) : there is no back door that I could find, to access the persistent state of the GUI, or build it up in a data-driven way. So making a mapping to keep our existing GUI XML working (and updating correctly) becomes a bit of a chore.

Kind regards,
James
