HI using:

  - type: glance
    title: Plafond spots woonkamer
    entities:
      - entity: light.living_ceiling_1_cds
        name: 1 Cd's
      - entity: light.living_ceiling_2_terrace
        name: 2 Terrace
      - entity: light.living_ceiling_3_wall
        name: 3 Wall

I expected to have a group toggle show, but it doesn’t. Thought id force it to, but even having

  - type: glance
    title: Plafond spots woonkamer
    show_header_toggle: true
    entities:
      - entity: light.living_ceiling_1_cds
        name: 1 Cd's
      - entity: light.living_ceiling_2_terrace
        name: 2 Terrace
      - entity: light.living_ceiling_3_wall
        name: 3 Wall

won’t do it:

I know it isn’t mentioned on https://www.home-assistant.io/lovelace/glance/ but feel this is an oversight. Shouldn’t we have a group toggle here? Would combine the super short glance with an extra nifty switch-all toggle.
