+So, finally we've got an integrated interactive, push-and-sometimes-shove router, although with a very limited user interface:
+
+- Edit->Interactive router launches the tool,
+- while routing: 'V' key places a via,
+- '+' and '-' keys cycle through available layers,
+- '/' key switches track posture.
+
+Via/track dimensions are taken from the netclasses. 
+There are no other options available for the time being - promise to add them soon :)
