On the feature board, in the small card size view, adding feature type icons would make it a much better view for getting an idea of what's going on in a release. Would be a nice alternative to text description of feature for the large card size view. Would work really well if used everywhere throughout the app!
I've a screenshot attached of what it would look like.
Highlight feature types
Quickly spot the different types of work your team is tackling. Add custom icons and colors to clearly see new features, improvements, and bugs.
