ahh, because task_id is the "real" id of a task

Yes the ID is a global system wide unique ID (regardless of the project etc.)

Maybe we will call tasks as

slug_yyyymmdd

Notice that you can just copy-paste the link in the address bar, it will bring you to the exact same view, meaning easily shared among users 🙂 You can, but I would actually use the Task ID. This also means that programatically you can do , task=Task,get_task(task_id_here) and interact and query and existing Task on the systemwdyt?
