I have a long list of features that I would like to see inside Blender, but instead of writing them all, I have decided in favor of the one I am missing the most: the ability to drag - adjust more than one loop slice. Currently you can only drag a single loop.
Considering that Blender heavily relies on the loop slice tool, that alone would be of great benefit to the modelling workflow. Of course, you can do something similar by scaling left and right, up and down or even use custom orientation modes to do so. But that’s just maybe because the process becomes really slow if not impossible on higher resolution meshes.
To illustrate the concept even better and to prove you cannot rely just on scale tool here is the fine example of what I am talking about:
Modo Loop Slice Tool(With three modes of operation: Free, Uniform, Symmetry)
I had already gone through a trial of Modo, so I can assure you that’s the way to do it. Of course, there are plenty of things I prefer in Blender, but loop slice is not one of them. If that’s just based on my experience, I would live with it but if not, please write your own feedback. The overall purpose is to improve the Blender, so even though I am not a developer, I hope with a right feedback, I can still rant to make it better.
