Refnotes dropzone in the page toolbar of notebook theme

My TW is using notebook theme and Refnotes plugin to manage my reference from Zotero.

My workflow is to use quick copy feature in Zotero to copy bibtex into clipboard and then paste in Refnotes dropzone. As it is a daily workflow, I configure the dropzone into Default tiddlers to avoid open sidebar menu, then Bioliography menu.

<div style="margin-bottom:8px;width:100%">
{{$:/plugins/kookma/refnotes/ui/dropzone}}
</div>

See figure below for an example.

I still have to jump to Default tiddler when I paste a new bibtex item.

Could I put the dropzone into Page toolbar in notebook theme?

For example, the green dash box below

No need very big box. An icon is good enough for me. Just need to click it and paste content into.

You have the freedom to place it wherever you prefer. Additionally, you can apply some CSS to manage its appearance and style.
