Hello, thank you for a great thing!
You know what would make your theme full-featured Project Manager?
Like, if two users work on a project, Admin 1 gets an email whenever Admin 2 posts a new ticket or update, and vice versa.
And if more users, then we need a bit more sophisticated system, for be able to choose which user gets notifications of which user's tickets and updates.
Please consider this for a new update.
