It seems that the headers used for each release visible in the Features>Board are fixed (and show the name and release date only). It would be useful to add information here to highlight the releases status while viewing the features.
Perhaps the header could be the compressed-view of the release card, which is of course already customizable.
Thank you for the idea. Given the low volume of support for this idea, we do not have plans to make updates in this area at this time. We hope you can understand.
