We use Taiga extensively and EPICs are our product management layer for our Safe Secure Cloud. We have built up a lot of stories linked to many EPICs. We would really value the ability to set a filter when viewing an EPIC to only show a subset of the stories based on their status.
Example - do not show completed stories and only show those stories in our Roadmap, planned and started or ready for PR Review.
This would be something you can set when viewing the EPIC or alternatively allow each user to set a preference for viewing EPICs to pre-filter
The same could also be said for Tasks and their status inside stories
This improves focus and reduces the friction and effort of finding and seeing what is left to be done and prioritise them
