Setting names of bones is physically impossible with current API. Also this wouldn't solve any problems, its not just about bones, scaling also matters, etc, etc.

Thank you so much for the reply, but I think I didn't explain myself properly. I don't want the tool to be able to set bone names, but for it to override the bone name it's looking for with another arbitrary one specified in the tool's menu, paying no mind to whatever broken stuff may happen. I realize this isn't so simple as I'm making it sound, but if the model I'm trying to merge is at least snapped to a bone and not just the pivoting, then one could at least scale/edit it down later manually, and it would at least move concordantly with said bone. Maybe it would be even better if we could also set those values (position/orientation/scaling) on the "advanced" menu itself as well for the really desperate people who don't want to download an SDK just to be able to attach a dumb model to another one.

I know this might hilariously multiply bad user feedback from people not getting how something works, the name based method is a good way to gatekeep complaints and keep it fool-proof, but maybe putting a big "ADVANCED OVERRIDE" and "Don't do this unless you're absolutely sure what you're trying to do! I will offer no support regarding this mode." along with some added clunkiness might scare away the general user from asking for help. I realize this is "Easy Bonemerge Tool", but there aren't any other non-easy bonemerge tools as powerful as I'm making them sound, right? If there are, I didn't find them.

I was also inspired to write this thread by using the "NPC Camera" tool that looks for joints/bones as far as I understood, and is also able to print all that info on the console allowing you to place a camera on any attachment that model has, which I think can be very well used as a template on how the feature I'm talking about should work.

If you think it might get a bit too cumbersome, I will understand that.
