Name of the tool always reflects the offset in mach. Tool number just calls up the slot of your turret. Offset is the one that sets up everything else. I am adding the tool number so if your macro is smart enough to detect the change of the tool dro without actually calling a tool change you can index to that position. Just adds more options is all. Options is the name of the game to please as many people as you can. 
That is only the case in the most recent versions of Mach, unless you are managing to do it yourself somehow? Up until very recently the tool number was what everything was tied to, with the way myself and Dan are doing the macro now it wouldnt matter, but before, it did.
Brian got fed up with my constant nagging and he gave in and did a couple of small changes, hope he caves in and does some more, CSS would be nice

Likely that wont happen until the next Rev though and no one knows when that will be, not even Brian I suspect.
