I hope I haven't just missed it ... but being able to add comments in a composition would be nice, and of course good programming practice. Sure, nodes can be labelled as well as given descriptive names. But in composition text would make a nice addition. This seems rather obvious so it is either possible and I haven't found it, or there is a good reason for not doing it.
ps: Also haven't found how to add information text to my sub-compositions.
Found myself wishing I could copy/paste values between node inputs. So currently when one right clicks on a nodes input value the options are "Edit", "Publish", "Fire" .... How about copy/paste. Perhaps no big deal for single values but a big time saver for multivalue items like points and transforms.
