Let users set a global default tag (or account‑level default) so every new Assistant thread is automatically tagged as specified.
Why it matters: I frequently lose track of important threads because they aren’t consistently tagged; a global default prevents accidental untagged threads and reduces lost/hidden data.
Open Assistant and create a new thread without first selecting a tag — the thread is untagged.
Select a tag in the Assistant sidebar, create a new thread — the new thread inherits the active tag.
