Edit Mode sekections & Mesh Edit tools
Prior to 2.8 you could use Ctrl-Tab to make a selection method, i.e. Vertex, Edge, Face. This functionality is changed to bring up the Mode Pie menu. Is there no shortcut key for Vert/Edge/Face selection.
Also when selecting a Mesh Edit tool from the Tool shelf is there no method for escaping/ending the operation. Also the function of some tools have changed, such as the Loop Cut when selected from the Tool shelf does not allow you to set the # of cuts with the scroll wheel, is this operation only available in the Tool Properties window
