Some thoughts

[glaprida]

It would be nice to be able to set some additional settings for the breadcrumbs, such as:

useId: true // defaults true. shows the #id of the element
showLabels: false // defaults false. if true, it should show the same label as in the layers panel instead of the tag name.
showIcons: false // defaults false. if true, it should show the elements icon (same as in layers panel)
appendTo: 'body' // css selector for where to append the breadcrumbs component

In my particular case I need all of this opposite to the defaults (the defaults I wrote up there are to keep the current behaviour).
I would be using {useId: false, showLabels: true, showIcons: true, appendTo: '#main-editor'}

It would also be great if when hovering the breadcrumbs the corresponding elements on canvas could stand out (same as with layers)
