UModeler 2.2 & 3.0 Beta has been release and it's available now.
2.2 includes lots of bug fixes, enhancements, new features and 3.0 beta. They can be checked out here - https://umodeler.github.io/releasenotes_UModeler_2.0.html#version-2-2
As it was announced UModeler 3.0 beta is about mainly the new menu system. All menu items are replaced with icons and they are operated based on context based system, which means that depending on which element tool among Vertex, Edge, Polygon and Object is enabled and which element is selected available tools are displayed in color.
Icon based menu can be enabled by toggling [T] off in the inspector.
3.0 will be released officially with new tutorial videos, manual and websites etc in a few months. I hope you'll give me as many feedback as you can in order to improve it until it's released.
The following video showcases the difference between 2.0 and 3.0.
Enjoy UModeler, tripolygon.
