It is more like English workbench in this regard, no vise yet. I can clamp a board to wide apron. Apron is 15 cm tall and worktop is 5.4 cm thick. So, there is plenty of place to clamp to it underneath.

But I usually do not plane edges like that. I prefer to shoot them, with the plane on its side (might not work for some wooden planes though).

That means that my workbench is very flat (used that #7 to flatten it) to use like that. And I also use workbench to check boards for flatness. That means that it is good when it is slightly bigger than the biggest piece I try to plane. Much faster to use flat workbench to check for twist than winding sticks (which I don't have), for example.
I wanted to add leg vise to it but it didn't happen yet and it works for me even without it.
