I have tried to reproduce the problem, but I failed. This is what I did (revision 6212): 1a) start in OpenGL canvas or b) start in legacy canvas 2) create a new board (2 layers by default) 3) use Layers Setup dialog to increase the number of layers to 4 4) switch to legacy canvas 5) draw a few tracks on inner layers 6) switch to OpenGL canvas, new tracks are visible > - Microvias layers are incorrect: currently, it is created from the top > to the bottom layer.

I have never used microvias before, so I should not argue about the constraints. I see the described issue now, it will be fixed. > - 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). There are two ways to insert vias in legacy mode: - based on the currently selected layer pair (Layer Pair dialog) - picking the target layer on every insert (as you mentioned) At the moment GAL offers only the first method, but I agree the second one seems to be more convenient. I will add it, but I guess it has to wait until the stable release happens, so it can be merged. What is the error message? I might be missing some information here. > Remark: I like the way blind/buried vias are shown in GAL mode.
