Short description of error
In this first file:
It is really difficult to distinguish that the front vertex is selected (that marked under the blue circle). In the other vertices it is also difficult to distinguish which of the vertices are in front or which are behind.
In this other file:
On the left, in Vertex select mode the edges coinciding with the blue Z and red X axis are almost invisible. On the right, in that view two of the vertices selected in front appear as not selected. The same in Edge select mode.
