YANG module designer tool

Hi folks, 
Just wanted to ask what are your favourite tools for designing YANG models
and why?
Are these two all there is:
https://www.mg-soft.com/mgYangDesigner.html
https://github.com/CiscoDevNet/yang-explorer

Or maybe some plugins for notepad++ or totalcmd/midnightcmd :)

Thanks a bunch.
