Has anyone gotten Tooledit gui working in PathPilot?

I am about to get a RapdiChange type tool changer running. (thanks to haskins-guitars/linuxcnc-rapidchange  for the code with some modifications) The Tx M6 stuff is all working but editing the tool2.tbl file is a pain (each tool needs a pocket # from 1-8) and then of course after editing you have to restart PathPilot.
The Tooledit gui is the answer but given that Mint 17 is rather ancient I was wondering if anyone has gone through this process already.
PathPilot recently moved to GTK3 so that is a bonus.
Standalone version is fine, it includes a Reload button to reload the configured tool2.tbl file.
The goal is to load up the toolchanger with tools for a program, edit Tool2.tbl, reload it and then run the program.

Thank you Andy.
I did get the .tcl version running, but it is tied to Axis so the Reload button doesn't appear for PathPilot.
I will give the python one a try, at least there is then a hope of tying it PathPilot somehow.
