Finder-style session labels: a hover button next to archive and pin, plus the native context menu, assign coloured labels to sessions; titles can take the first label's colour or a label symbol; the view options gain a filter by label that applies before grouping. Labels are stored by the Host and shared across workspaces.
This plugin has not published an npm package, so the store does not offer an install command yet. Use the repository link below to view the source.
