A thought about the tool table: How about we get rid of it?
Tool+spindle+feed speed are really attributes of each individual path (in the end the only place where they really matter). Let's say you create a profile and as part of that you select a tool (+ spindle and feed speed). The default could still be the same tool the previous path used, otherwise a tool can be selected from a number of places:
* create a new one
* any tool previously used in the job
* any tool previously used in a different job of the same document
* any tool from a list of tool libraries
* any tool from a list of tool changer setups
* default settings of the Path WB "Preferences"
The job can insert TC commands as required. The tools used by a job can be exported as "tool changer setup" for later jobs, as a new tool library or integrated into an existing tool library.
The only place a user has to deal with indexes is when the tools get exported for a tool changer, otherwise the job can assign an index to each tool as it sees fit and create a list of id=tool.
A tool library is where the feed and spindle speed recommendations come in, add filters for materials and machine .... all the fanciness one desires
