Create vertex on a desired part of an edge Ctrl + R creates vertex exactly between two vertices of an edge but I want it in the place where I click, that is any part of an edge where I click. I wanted to know if there is any such feature available in blender. This will just increase my modeling speed.
It's true that CtrlR works a bit different for single edge like this other than loop cutting on faces, since it is not designed for that. However, you can select that new vertex then GG, or ShiftV to slide it along the edge.

Furthermore, a new coming feature may benefit such workflow. Just FYI.
