- [ ] Suggest a design in the issue and get approved. I suggest a block with `--text-color` background and small arrow on top. - [ ] Add `<Tooltip>` component. - [ ] Use new `popover="hint"` API for it. - [ ] Add it to `<Button>` and `<NavbarItem>` for `size=icon`. - [ ] Add story by calling `mouseenter` event.
