It would be wonderful if RD worked in TSW5! (and 6). The fix seemed simple in TSW2 and TSW3; TSW4 is a little wonky but still usable. I have been looking for RD optimization to show up in the Roadmap for a year now.
and it would be even nicer if someone who is working on their custom raildriving panel thing would one day commercialize the solution... I mean, sure, it would be expensive just like RailDriver is cos it is super niche, but then, if it worked and for long, wouldnt mind shelling a major buck for it
