The ability to add a Note to a specific Object within a board. Currently the only option is to add a comment which isn’t practical if you just want to add details about a particular Object. It would be useful if you were able to then turn on Comments or Chat regarding the Note if required so that a discussion regarding a particular process can be documented and then set to Resolve when agreed.
It isn’t a huge leap from Comments but it would allow for easier documentation and discussion of specific processes.
