I use DEVONthink Pro Office to house research performed across the web. There is an extension for other browsers I can use to save sites as bookmarks, PDFs, WebArchives, etc. Having that extension on Brave would be awesome.

Not that you will get anything out of it but that is an original thread about it
Now we just need a dev to make a request on github about it
Request added here
