I've released a new version that fixes the Autoconnect "scrolling through the combobox" issue; and you can now connect nodes by rightclicking in the RmpView (If Autoconnect is checked, it will also try and create the reverse link too).
I have been thinking about redesigning some of this tool to work better with OpenXCOM data, and merge with M.A.R.S. (I don't know if you've been following the other OXCTools thread). After all, one of the issues on my repo is remove "unused UFOs", but if we use OXC ruleset data, we will only process valid data anyway.
I'm not sure on timescale for that merge, but you'll start to see a MARS binary join the distribution folder when it's a bit further down the line
