The GUI library QML.jl was just released in version 0.8.1.
It allows to create complex and beautiful GUIs using a syntax similar to JavaScript. It has GR and Makie integration.
This release contains mainly bug-fixes and documentation updates, but it is still an important milestone because now all examples work and no known bug is left.
Create your own packages on top of QML.jl !
