Bibliography reference management and automatic footnotes when copying and pasting from a website

In another thread has been discussed about footnotes (strictly speaking they would be endnotes). It’s been suggested there (and I’ve seen this in other app forums as well) that this might be possible with manual hyperlinks, but I think it would be great if the reference manager was built into the app.

In the same way, many will know that when you copy content from the web and paste it into onenote, a note appears below that says “from: <www.site.com 1>”. The same function would be great, but for the reference to appear in the footnotes (“endnotes”).

I’ve been thinking for a long time that such an app would immediately appeal to all scholars / writers.
