3. font icon
`<span class="icon-wrench"></span>`
This should be the same as all the other uses of font-icon
` <span class="icon-wrench" aria-hidden="true"></span`
4. I appreciate that the text is "toolbar" and that makes sense but the wrench icon is really more for tools/utilities/options. If you dont want to use a burger icon here then how about https://fontawesome.com/icons/caret-square-down?style=solid
5. there may be more issues I stopped at this for now
### Styling issues
1. When this is made into a real button then it will need the appropriate btn classes obviously. It already has classes `class="btn btn-subhead ` but the class `btn-subhead` doesnt apear anywhere in the css. I am guessing that thi8s might have supposed to been `btn subhead` as I can see js code ` const subHeadToolbar = doc.querySelector('.subhead');` but thats just a guess
It took me ages to find the toolbar in any of the list views until I randomly clicked on a piece of text that had no styling etc
Accessibility Problems
<button>
not an<a>
a:not([href]):not([tabindex]):focus { outline: 0 }
