Status: RESOLVED FIXED

Description

[Patrick Brosset <:pbro>]

It's one of the lesser used tools, and we don't want the sidebar to look too crowded, so let's move it last.

Looks good to me, thanks for updating the implementation!

options.insertBefore defaults to undefined. This means we will actually query "#sidebar-alltabs-item-undefined". It is unlikely to clash with an actual id, but it could.

To be on the safe side I would structure this code as follows:

if (options.insertBefore) {
  let referenceItem = menu.querySelector(`#${idPrefix}${options.insertBefore}`);
  menu.insertBefore(item, referenceItem);
} else {
  menu.appendChild(item);
}

If referenceItem is falsy, insertBefore will behave in the same way as appendChild, so we are safe even if an invalid id is provided.

same remark as for the other if statements
