**Short description of error**
New clamp option (shortcut C while using vertex slide) doesn't do anything, it's impossible to toggle it off.
Impossible to slide vertex along the extension of the edge away from the other vert defining the edge.
Ability to select the direction vertex moves is lost, making the workflow very hit and miss and forcing to cancel GG slide or vertex slide often.
