Orson,

Could you have a look at these few issues:

- When the number of layers is increased (for instance from 2 to 4
layers), the tracks drawn on the new layers (for instance usung the
legacy mode) are not displayed in OpenGl mode , until the board is
saved, Kicad closed and reopened.
- Microvias layers are incorrect: currently, it is created from the top
to the bottom layer. This is incorrect.
It can be discussed, but a microvia is usually created between 2
adjacent layers, and in Pcbnew, it is restricted to an external layer to
the near inner layer. Change it needs adding code in DRC and to manage
uvia sizes and holes diameter depending on the number of layers and
their thickness.
And this option makes sense for microvias on pads, which are really
restricted to the external layer to the near inner layer.
- blind/buried vias cannot be inserted (always an error message).
  When inserting a blind/buried via, the target layer choice should be
shown (and/or the dialog to choose the layer pair should be accessible
in GAL mode).
  My preference is just show the target layer choice (see legacy mode).

Remark: I like the way blind/buried vias are shown in GAL mode. Perhaps
a similar way could be used for microvias ( which are in fact just
blind/buried vias with a specific size)

Thanks.
