I can confirm that none of our objects have inlet & outlet assist messages. The tl;dr explanation is that adding this in a sane way requires an internal refactor, and that because this is a Max-only issue and there were always more pressing problems to sort out, it hasn’t been moving up the priority list. This may be your moment to file our first GitHub feature request…
I’m unreasonably excited to have both a fixed bug and a feature request up. I’ll review the help files and see where things can be improved, but – like you – I do appreciate it when hovering over an in/outlet tells me things.
There would be a Max-only kludge one could do, but I wouldn’t be able to get to that especially soon either.
However, if any readers who yearn for inlet / outlet assistance fancied putting in our first pull request, I’d be totally happy to help them through it. (Don’t worry Rod, I’m not expecting you to suddenly become enthusiastic about C++ )
