#1 Why u drop the project?

i did not drop it. i do not need it at the moment and apparently no one else does. so there's no movement right now. do you have any plans for libgtkflow?

I'd love to see it used for K-3D but bart hasn't even had time to finish port from gtk2 to gtk3 yet.

Internally everything is a node there, but it currently just shows everything in a stack. K-3D sadly looks to be pretty much on life support as a project though, since it has no active contributors/maintainers and since I guess it's difficult to compete with blender for the niche type of developer it takes for developing 3d DCC suites.

edit: interestingly it did just get an update to it's homepage(looks like its using github pages now?) /edit

I do think it would be an excellent project to demo the use of libgtkflow though.

I'm about to try it soon ;)

I think its better to rewrite it on GTK4 first, also I found https://github.com/aluntzer/gtknodes and its port to C# https://github.com/AliensGroup/Gtk.NodeGraph, but it looks less smooth.
