Hi Anders,
My Kite Design plugin www.karorocad.com was first developed with HumanUI, but I was very keen to get it to work cross platform.
I did try Synapse, but like ETO that it is based on I found the learning curve too steep to make any real progress.
What I ended up doing was developing my own HumanUI replacement based on Webview:
This has been my production code UI since the start of the year, has needed some tweaks to work in R8 but I’m pretty happy where it is now at.
I’ve been toying with the idea of compiling the UI as a GH plug-in to offer as an alternative to HumanUI. UI+, Synapse etc, but time is a factor here. Watch this space as the winter (development time) progresses in Cape Town.
Cheers
DK
