I'd like to store decision logs (beyond just the feature priority). It may be target markets, initial decisions that you want to store and map to a feature or initiative, whole bunch of things that are stored today in XLS And difficult to maintain and keep up to date. Bit like notes but a little more flexibility to include specific fields and tag to products and features...
We recently rolled out a feature called Custom Tables which exists in our Enterprise+ plans. This allows you to extend the data model of Aha! to model and track information in Aha! that may be important to your organization (like your decision logs).
You can track this information and link it to Product, features and any other standard objects in Aha!
