Aha! Ideas is great for collecting ideas for new features.
Co-founder & CIO - Enplug
Aha! is a smaller product development tool that we use to track initiatives and incoming company ideas provided by non developmental or engineering employees. It was our original project development tool but lacked the integrated codebase and the ability to build out test cases, so we migrated to JIRA.
