I dont like to route the board in mm, I allways route in inches, even when I 
have mm footprint. Because of the wonderfull resource that atracts the cursor 
to the pin, even when he is outside the grid, I really never needed to modify 
my grid setting (I normally route with 25 mils).
What I miss is a resource to lock the grid settings. Thats because I use a lot 
the F key (to look hows attached to a net) and F is the key next to G, so is 
common to press G when I wanted to press F. The grid become 30 mils and the 
route becomes strange. Normally I have to unroute a lot of work because I did 
it in 30 mils...
