Seems a bit odd that users need a paid seat just to add tags to features so they can have meaningful views of work that relates to their dependencies or needs. We could like to enable this without having to 10x our cost of paid seats; it will become barrier for us to use Aha.
Thank you for the idea. We currently have 4 tiers of users permissions within Aha! (product owners, contributors, reviewers and viewers). We have spent much time gathering feedback from the community in constructing these permission levels. As noted, the Reviewer role provides the ability to view work through custom views. One suggestion would be to have the reviewers use other filters which leverage data already entered on a feature by a product owner or contributor.
At this time, we do not have plans to make changes to the user permissions model based on community feedback and our current priorities. We hope you can understand.
