Could a tool like AngularJS or VueJS or React help in significantly customizing the Craft admin interface? Could it help add additional functionalities?
For instance, let's take the example of adding external links to a post. Vox Media's Chorus lets writers save links in a browser bookmarklet (during their research process), and then pop it on the sidebar in their CMS admin interface when the writer clicks on the bookmarklet. The writer could now just select a phrase in his copy, and then click on a link in the sidebar and have it added to the text automatically. No selecting the text and then clicking on Add link and then copy-pasting the link. Lot of steps reduced.
The above cannot be done on Craft by default and in my research I haven't found a plugin that enables such a functionality.
Could the admin interface in Craft be altered to include such functions that aid in speeding up the editorial workflow?
