Currently you can only remove variable ports in the Merge Variabel node from the bottom. question is would it be possible to make this removal more flexible so as to also be able to remove a port in the middle. I think this is possible with other nodes that have a flexible number of ports.
This is actually not specific to this particular node but to any node having an “extensible port group”.
Ports and port groups are in fact a surprisingly intricate topic. I’d have to research a bit to be able to say whether this was a UX decision for Classic UI or whether there are deeper technical reasons for it. In any case, I’ll elaborate.
just as a quick update, we don’t immediately see any big blockers there. I think we might get that into one of the next patch releases (NXT-3164) – but do not understand this as a guarantee, because we are obviously always very very busy building all sorts of good stuff
