Seams like https://cos.nyghtfalcon.com/pm-test is a blank page?
Also, public visitors need to login to be able to use the plugin generated by the shortcode (if not logged in they see a link to a login-page). Every user needs to be setup as a WordPress User (subscriber is ok).
Yes, task templates is a great idea, I’ve been working on that some time but it still needs many more hours.
Yes, group tasks into a project is also a great idea, I call that sub-tasks and I’ve been working on them some time too. They too need more hours.
Notifications can be done with hooks, I’ll try to add them later.
So, to become the plugin you need I would probably need 40-50 more hours of coding. Unfortunately I don’t know when that would happen since I have a family to support and pretty much no time to work pro-bono.
I hope you can find what you’re looking for.
If you think the shortcode functionality works ok, I’ll update the WP Respository version.
Take care,
Klas
