Thanks for this functionality. I've already colour coded one of our projects. My feedback is as follows:
1) limited colours may make this functionality less useful for larger projects.
2) the functionality still doesn't allow for colour coding of the issue type i.e. epic (that remained purple). This is not useful when looking at your list of epics. Being able to colour code the list would add additional value and add back the functionality that exists as stardard for non Next-Gen projects.
Thank you.
