How do I download all games from one user?

Title says it mostly.
I want to queue all the games owned by one user and download them. Currently recent games only gets a few of the games I actually want.

Since this app seems to not be actively developed, you could also take a look at my project https://github.com/tpill90/steam-lancache-prefill
It supports what you're looking for out of the box, just passing along --all to the prefill command will start prefilling your entire steam library.
