Labels sit in the sidebar, under Inbox, Library, Archive, and Highlights.
Add a label
Type a name in the New label field in the sidebar and submit it. The label appears in the list.
You can also add a label from the reader, using the label field on the article.
Filter by a label
Choose a label in the sidebar. It filters the list you are already in. From Inbox, the label shows unread articles with that label. From Library or Archive, it shows articles in that place with that label.
The number beside a label is how many unread library articles carry it.
Put a label on an article
Drag an article from the list onto the label. If it already has that label, nothing changes.
You can also add a label from the reader, or add one label to several selected articles. See Several articles at once.
ReadMeliora offers undo after you add or remove a label.
Delete a label
Open Settings, then Labels. Each label shows how many articles use it. Choose Delete and confirm.
Deleting a label takes it off every article. The articles stay.
Feed items arrive with the label RSS. Removing the RSS label does not unsubscribe the feed. Remove the feed under Settings, then Feeds. See Feeds.
