Those masso wanks still don't have tool radius comp I would like to see a wear comp along with cutter radius/diameter, while we're on that subject. Also, as Jeremie mentioned, Siemens controls allow you to call up a tool by number: T6 M6 or by name: T="My Tool". Similar functionality would also be a welcomed addition... As would goto 😏.
