Migrate entries to Gears icon in toolbar

Continuing the discussion from Formatting toolbar:

I’ve noticed our users are confused about how to Insert Date / Time or Jitsi Video Call component based on the icons in the toolbar alone.

I’d like to migrate some options into the “Gears” or Options icon in the toolbar in order to simplify the layout.
How would I change the gear icon? I’m thinking a + symbol will be more clear.
or, add a descriptive word or two alongside the icon.

I like the way entries within the gear icon also include words describing what they do. Thanks for any tips or advice.
