Any chance of the Manage Curve Collection (or any type of data - breps, points etc.) dialogue getting some upgrades? Would be nice to pick an item in the collection and highlight it in the viewport. That dialogue box already allows you to rearrange the items - actually seeing which item you’re working with would help a lot, same with deleting items.
Also having an option to display an index number alongside the items in the view port would help to see at a glance what’s going on. Then you could also rearrange items and see their corresponding index change in the viewport. Sometimes with a smaller collection of items I don’t always want to sort them with additional nodes - easier to just rearrange in that MANAGE X COLLECTION dialogue box.
