I use the Labels to indicate task status
(pending/active/waiting/completed)
By using Labels instead of Custom Metadata, the status can be accessed in DTTG
For me, labels indicate what I’m supposed to do with a given document. Blue stands for “more research”, Orange for “missing information”, etc. No label if a document does not require special attention.
For me, I use labels to show the status of a piece of writing or blog post. First draft, Final draft, Proofread, Posted on Web.
I don’t use star rating. I briefly played with it to show a scale of importance - but it was too messy and I stopped. I use a simple important tag now.
