It would be nice to have the ability to vote on feature cards that Product Managers have created within a given project within AHA. This way the functionality would not be limited to votes on features that have been promoted from the Ideas Portal submissions. This would also allow for Product teams to vote among themselves on the features they see as most valuable.
Thank you for your idea. As you noted, voting is currently a capability specific to ideas. One way to handle the internal voting would be to create a product where you keep ideas for internal teams to vote on. Another suggestion would be to leverage the Aha! score. While this is not voting, it does provide a way to add a quantitative measure of a feature's value. This can then be used to help with prioritization.
At this time given historical feedback and the current capabilities mentioned above we are unlikely to implement this idea. We hope you can understand.
