It would be useful if Aha would add a "grouping" capability for Features, while that grouping must not be related to any particular Release.
Eg. for one product I do have today ~400 features in planning and backlog. They are spread out across 3 different planned (roadmap) releases and different backlog (parking lot) releases. Multiple different Features, from all different Release might belong together, but there seems to be no good option today OOTB in Aha, to group those different Features together into a single Feature Group.
With having such Release independent Feature Groups, it would be possible to manage the superset of all Features with a much easier overview, in maybe ~20 Feature Groups, rather than ~400 single Feature entries.
Those Feature Groups could be presented as tiles (with configurable details and size) on one screen. Each Feature Group could present it's completion status in % or number of Features delivered vs total, and an ETA for Feature Group completion in case each Feature has a Release and thus target date assigned.
